If the fractions have a common (same) denominator, you simply subtract the numerators
Example 5/8 - 3/8 = 2/8 or 1/4
If the fractions have different denominators, you have to convert the fractions to ones that have the same denominator (the least common denominator) and then subtract.
Example 5/8 - 2/5 = 25/40 - 16/40 (multiply the first by 5/5 and the second by 8/8)
with the result 9/40. (check to see if the answer is reducible)

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.

It means you have to subtract 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.
it stay the same when you subtract fractions and when you add fractions.

You need a common denominator in order to add or subtract fractions.
You don't

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
