Is it always necessary to find the least common denominator to compare the sizes of 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 .
When you are multiplying fractions do you find the common denominator?
no
How do you add improper fractions if the denominator can't multiply into the other denominator?
You Ned to find a larger common denominator or multiply the denominators to gain a common denominator.
How do you subtract fractions in simplest form?
You first need to find a common denominator, not necessarily the least common denominator. Next, you rename the fractions according to the common denominator. Only then can you subtract the fractions. After subtraction you should simplify the answer.
Do you have to find a common denominator to subtract fractions?
Yes.
Find a common denominator for the pair of fractions. Then, write equivalent fractions with the common denominator?

Why do you have to find a common denominator?
Addition or subtraction of fractions require "like" fractions: that is, fractions with the same denominator.
How do you add or subtract dissimilar fractions?
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.

How to do inequality fractions?
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.
Adding unlike fractions?
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.
