What is 3 1/2 minus 2/3?
Next, we multiply the whole number by the denominator. 3 x 2 = 6. Step 3 - Add Numerator. Then, we add the numerator to the answer we got in Step 2. 6 + 1 = 7. Step 4 - Solution. Finally, to get the solution, we keep the original denominator and make the numerator the answer from Step 3. Thus, 3 1/2 as an improper fraction is. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 3 ? 2 = 6. In the next intermediate step, the fraction result cannot be further simplified by canceling. In words - two thirds minus one half = one sixth.

You can find more information about the Yahoo Answers shutdown what is 3 1 2 whqt to download your data on this help page. To regroup, you take 1 whole. First you have to make the bottom numbers the same before you can create a solution. You have to find a number the lowest possible they can both be divided into without a remainder. So 2 and 3.
Lowest number they can divided into lowest 'common denominator would be 6. Sometimes multiplying the bottom numbers of the fraction like in this case will give you the lowest common denominator. Now you need to eliminate the whole number 3 to get it to make sense to subtract.
In this case and all cases you multiply the bottom number 6 by the whole number 3 then add the top number 2. The bottom number in what is a killer whales prey case doesn't change. Now you divide the top by the bottom. The remainder 4 after you divide will then go on top of the number that stays the same. Hope this helps. Trending News.

3 = 1 · 1. /. 2 · 3 = 1. /. 6. Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 3. /. Jun 17, · 3 1/2 is also (bcoz 1/2 is 1 divided by 2 equals.5 or) 2/3 of is (/3 = or 1/3) then x 2 = ) Then - = or 1 1/6. I hope this is very helpful to all of you. Thanks. Converting from decimals to fractions is straightforward. It does however require the understanding that each decimal place to the right of the decimal point represents a power of 10; the first decimal place being 10 1, the second 10 2, the third 10 3, and so on. Simply determine what power of 10 the decimal extends to, use that power of 10 as.
Below are multiple fraction calculators capable of addition, subtraction, multiplication, division, simplification, and conversion between fractions and decimals. Fields above the solid black line represent the numerator, while fields below represent the denominator. In mathematics, a fraction is a number that represents a part of a whole. It consists of a numerator and a denominator. The numerator represents the number of equal parts of a whole, while the denominator is the total number of parts that make up said whole.
For example, in the fraction 3 8 , the numerator is 3, and the denominator is 8. A more illustrative example could involve a pie with 8 slices.
If a person were to eat 3 slices, the remaining fraction of the pie would therefore be 5 8 as shown in the image to the right. Note that the denominator of a fraction cannot be 0, as it would make the fraction undefined. Fractions can undergo many different operations, some of which are mentioned below. Unlike adding and subtracting integers such as 2 and 8, fractions require a common denominator to undergo these operations. One method for finding a common denominator involves multiplying the numerators and denominators of all of the fractions involved by the product of the denominators of each fraction.
Multiplying all of the denominators ensures that the new denominator is certain to be a multiple of each individual denominator. The numerators also need to be multiplied by the appropriate factors to preserve the value of the fraction as a whole.
This is arguably the simplest way to ensure that the fractions have a common denominator. However, in most cases, the solutions to these equations will not appear in simplified form the provided calculator computes the simplification automatically.
Below is an example using this method. This process can be used for any number of fractions. Just multiply the numerators and denominators of each fraction in the problem by the product of the denominators of all the other fractions not including its own respective denominator in the problem. An alternative method for finding a common denominator is to determine the least common multiple LCM for the denominators, then add or subtract the numerators as one would an integer.
Using the least common multiple can be more efficient and is more likely result in a fraction in simplified form. In the example above, the denominators were 4, 6, and 2. The least common multiple is the first shared multiple of these three numbers. The first multiple they all share is 12, so this is the least common multiple.
To complete an addition or subtraction problem, multiply the numerators and denominators of each fraction in the problem by whatever value will make the denominators 12, then add the numerators. Fraction subtraction is essentially the same as fraction addition. A common denominator is required for the operation to occur. Refer to the addition section as well as the equations below for clarification.
Multiplying fractions is fairly straightforward. Unlike adding and subtracting, it is not necessary to compute a common denominator in order to multiply fractions. Simply, the numerators and denominators of each fraction are multiplied, and the result forms a new numerator and denominator.
If possible, the solution should be simplified. Refer to the equations below for clarification. The process for dividing fractions is similar to that for multiplying fractions.
In order to divide fractions, the fraction in the numerator is multiplied by the reciprocal of the fraction in the denominator. The reciprocal of a number a is simply 1 a. When a is a fraction, this essentially involves exchanging the position of the numerator and the denominator. The reciprocal of the fraction 3 4 would therefore be 4 3. It is often easier to work with simplified fractions. As such, fraction solutions are commonly expressed in their simplified forms. The calculator provided returns fraction inputs in both improper fraction form, as well as mixed number form.
In both cases, fractions are presented in their lowest forms by dividing both numerator and denominator by their greatest common factor. Converting from decimals to fractions is straightforward. It does however require the understanding that each decimal place to the right of the decimal point represents a power of 10; the first decimal place being 10 1 , the second 10 2 , the third 10 3 , and so on.
Simply determine what power of 10 the decimal extends to, use that power of 10 as the denominator, enter each number to the right of the decimal point as the numerator, and simplify.
For example, looking at the number 0. This would make the fraction , which simplifies to , since the greatest common factor between the numerator and denominator is 2. Similarly, fractions with denominators that are powers of 10 or can be converted to powers of 10 can be translated to decimal form using the same principles. Take the fraction 1 2 for example. To convert this fraction into a decimal, first convert it into the fraction 5 Knowing that the first decimal place represents 10 -1 , 5 10 can be converted to 0.
If the fraction were instead 5 , the decimal would then be 0. Beyond this, converting fractions into decimals requires the operation of long division. In engineering, fractions are widely used to describe the size of components such as pipes and bolts. The most common fractional and decimal equivalents are listed below.
