How do you minnous fractions?
Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

What is the rule in adding fractions having the same denominator?
Sum of the fractions = sum of numerators divided by their common denominator. Adding Fractions rule implies to addition of fractions having same denominator and as well as adding fractions with different denominators. So rule for adding fractions having the same denominator is add the numerators and simplify For example : 3/5 + 2/5 + 9/5 = (3 + 2 + 9)/5 [add the numerators] = 14/5
How do you add and subtract proper fractions?
If the denominators are the same, add or subtract the numerators. If the denominators are different, convert them to a common denominator and add or subtract the numerators. 2/3 - 1/3 = 1/3 4/5 - 2/3 = 12/15 - 10/15 = 2/15
How do you you do the mathematical operations in fraction?
To add or subtract fractions, or even just to compare them (verify which fraction is greater), you must first (1) find a common denominator, and (2) convert both fractions to equivalent fractions with the common denominator. Then you just add, subtract, or compare the numerators. For example, 2/3 + 1/6 = 4/6 + 1/6 = 5/6. To multiply fractions, multiply the numerators and denominators separately. For example, 1/3 times 2/5 = (1x2)/(3x5) = 2/15. To divide fractions, multiply the first fraction by the reciprocal (multiplicative inverse) of the second fraction. If the fraction consists only of the numerator, you get the reciprocal by exchanging numerator and denominator. For example, 1/3 divided by 2/5 = 1/3 times 5/2.
How do you mutiply fraction by fraction?
The numerator (top) of the answer is the product of the numerators of the two fractions. The denominator (bottom) of the answer is the product of the denominators of the two fractions. You may then need to simplify.For example,2/5 * 3/8 = (2*3)/(5*8) = 6/40 = 3/20The numerator (top) of the answer is the product of the numerators of the two fractions. The denominator (bottom) of the answer is the product of the denominators of the two fractions. You may then need to simplify.For example,2/5 * 3/8 = (2*3)/(5*8) = 6/40 = 3/20The numerator (top) of the answer is the product of the numerators of the two fractions.

When 2 or more fractions have same denominator?
If you are adding or subtracting fractions with the same denominator, you can add or subtract the numerators and keep the denominator the same. 1/8 + 3/8+ 3/8 = 7/8, for example
How do you compare two fractions whose numerators are the same?
If the fractions have the same numerator (top number), then the fraction with the larger denominator (bottom number) is the smaller fraction, which implies that the fraction with the smaller denominator is the larger fraction. For example with 1/2 and 1/4, it can be easily seen that 1/2 is the larger of the two.
How do you add and subtract proper fractions?
If the denominators are the same, add or subtract the numerators. If the denominators are different, convert them to a common denominator and add or subtract the numerators. 2/3 - 1/3 = 1/3 4/5 - 2/3 = 12/15 - 10/15 = 2/15

How do you put different fractions in increasing order?
Option 1: Find a common denominator for the two fractions. It need not be the least common denominator; for example, for two fractions, if you just multiply the two denominators, you get a common denominator. Convert all the fractions to the common denominator. Then you can compare. Option 2: Convert each fraction to decimal, by dividing the numerator by the denominator. Then you can compare the decimals.
How do you compare fractions with the same numerator and different denominator?
If the numerators are equal, then here's what the denominator will tell you: The number with the largest denominator will will be the smallest number. For example: Compare 1/3 and 1/4. 1/4 is smaller because it takes 4 of those to make up 1 whole, while it only takes 3 thirds to make a whole. If the numerator is another number, the principal is the same, as long as all fractions have the same numerator.

To subtract fractions that have common denominators subtract their?
Subtract their numerators, and put on top of the common denominator. Thus, for example, 5/3 - 3/3 = 2/3. Works for addition, too (add the numerators).
How do you multiply disimilar fractions?
To multiply two fractions, the numerator (top part) of the result is the product of the numerators, and the denominator (bottom part) of the result is the product of the denominators. There is no need to convert to a common denominator first; this is only necessary to add, subtract, or compare fractions. For example, 1/2 x 5/7 = (1x5) / (2x7) = 5/14. Note that it is easier to do any simplifications BEFORE doing the actual multiplication.
Why is it easier to add fractions when they have the same denominator?
Because all that is needed is to add the numerators as for example 3/12 plus 4/12 equals 7/12
