28/37 = 2520/3330
31/90 = 1147/3330
2520 - 1147 = 1373
The answer is 1373/3330
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.

You don't
It means you have to subtract fractions.
subtracting fractions
Because you can't add or subtract fractions that have different denominators. Making them like fractions, by multiplying so the denominators are the same, you can add and/or subtract them.
no, to add and subtract like and unlike fractions the denominator has to be the same,
Just subtract the numerators and copy the denominator
by finding the common denominator of the fractions
