Suppose the two fractions are a/b and c/d ad that b, d > 0.
Then cross multiplication gives ad and bc.
If ad > bc then a/b > c/d,
If ad = bc then a/b = c/d, and
If ad < bc then a/b < c/d
Convert unlike fractions to equivalent fractions with common denominators by finding the LCM of the denominators.
Unlike. Unlike. Unlike. Unlike.
Multiply all numerators to get numerator of the product. Multiply all denominators to get denominator of the product. This is true whether the factors have like or unlike denominators.
you make them have like denominators by multiplying so many times that they have the same denominators or you can make them have like denominators by multiplying the two
Like fractions have the same denominators (bottom part of fraction), unlike fractions do not.
Because when you compare fractions with the same denominators, you do not have to find the least common denominator (LCM or LCD).
Multiplying the denominators together of two or more unlike fractions will get you a common multiple.

It depends what you are doing with the fractions. If you are multiplying or dividing fraction, the denominators do not need to be the same and the calculation can be carried out immediately. If you are adding or subtracting fractions, the denominators must be the same; if you have different denominators, the fractions must first be changed into equivalent fractions with the same denominator. When the denominators are the same (or have been made the same as equivalent fractions from being different) the calculation can be carried out.

fractions having same denominators are like fractions & others are 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.

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.
