For the denominator, multiply the denominators together.
For the numerator, subtract the second numerator multiplied by the first denominator from the first numerator multiplied by the second denominator:
a/b - p/q = (a x q - b x p)/b x q
eg:
6/7 - 3/4 = (6 x 4 - 7 x 3)/7 x 4
= (24 - 21)/28
= 3/28
To combine the fractions or subtract the fractions. Same method with mixed numbers.
it stay the same when you subtract fractions and when you add fractions.
Oh, dude, the butterfly method, or the method of cross-multiplication, works in math because it's just a fancy way of multiplying fractions. When you're multiplying fractions, you're essentially multiplying the numerators together and the denominators together. So, the butterfly method is just a cool visual way to do that. It's like math's way of saying, "Hey, let's make multiplying fractions a bit more interesting."

it works when comparing fractions by multiplying the fractions to see whitch one is greater not greater and equal
The three-step method is the easiest way to subtract fractions. First, ensure that the bottom numbers, or denominators are the same. Then, subtract the numerators.Place the answer over the same denominator. All one needs to do now is simplify the fraction.
it stay the same when you subtract fractions and when you add fractions.
Make the fractions equivalent then subtract

multiply the fractions until they have common denominators and then subtract them
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.
