find GCF(Greatest Common Factor) then subtract
It is an instruction for you to carry out the arithmetic operation of subtraction on fractions whose denominators are not the same.
convert at least one of them so that they have the same denominator, then proceed with the addition or subtraction
No. If the denominators are the same, you subtract the numerators. If the denominators are different you have to find the least common denominator.
If the denominators are the same, subtract the numerators. If the denominators are different, convert them to equivalent fractions with a common denominator and subtract the numerators.
If the fractions have the same denominator, add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible. If the fractions have different denominators, find the LCM of the denominators and convert the fractions to equivalent fractions with like denominators. Then add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible.
The denominators need to be the same for subtraction. Find the Least Common Denominator for both items and then subtract.

the noun for subtract is subtraction
Having learned how to do subtraction, he could subtract one number from another.

If the denominators are the same, subtract the numerators. If the denominators are different, convert them to equivalent fractions with a common denominator and subtract the numerators.
The same way you would add or subtract whole numbers, leaving the denominators alone.
SUBTRACTION: You first turn both mixed numbers into improper fractions. If needed, change the denominators into like denominators. Next, subtract the two improper fractions and reduce if necessary. ADDITION: If needed, turn denominators so they are the same number. Next, add and reduce if necessary.
