You Ned to find a larger common denominator or multiply the denominators to gain a common denominator.

To compare two fractions, find a common denominator, then convert each fraction to equivalent fractions with that common denominator. Finally, you compare the numerators. 5/6

It helps to find a common denominator and multiply both sides of the inequality by this common denominator. That way, you have an inequality without fractions.

Common denominator

First find the lowest common denominator and then adjust the fractions accordingly before subtracting the numerators

Multiplying fractions is quite different from adding them. You just multiply the numberators and the denominators separately. You can find the common denominator if you like, but in the end (after simplifying), you'll get the same result, and the additional work of finding the common denominator and converting the fractions turns out to be unnecessary. Try it out for some fractions!

no. you can multiply straight across in fraction multiplication

When you're dividing fractions ... or multiplying thrm ... they don't need to have the same denominator.

Note: numerator is the top part of the fraction, denominator is the bottom part. 1) Find a common denominator. It may be the least common denominator, but it need not be; just multiplying the denominators also gives you a common denominator, not necessarily the smallest one. 2) Convert each fraction so that it has this common denominator. This means multiplying numerator and denominator by the same number.

Addition or subtraction of fractions require "like" fractions: that is, fractions with the same denominator.

To add fractions, you have to find their common denominator by multiplying the two denominators together and one of the numerators to the others. Then you add just the top numbers together.

It's essentially the same process as finding the least common multiple of whole numbers. Example: 1/30 and 1/42 Factor them. 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Combine the factors, eliminating duplicates. 2 x 3 x 5 x 7 = 210, the LCD

When adding and subtracting unlike fractions, it is necessary to find the LCM of the denominators, called the least common denominator. Once you have found the LCD, you can convert the fractions to equivalent fractions with a common denominator and proceed with the adding and/or subtracting. Finding an LCM will have no effect on multiplying fractions.

When comparing fractions you must find a common denominator; by finding the least common denominator it will keep the numbers (numerators and denominator) smaller .

You first convert them to similar fractions, i.e., to fractions that have the same denominator.* Step one: find a common denominator.* Step two: convert both fractions to equivalent fractions that have that denominator.

You can always find a common denominator by multiplying the denominators together.
