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.
multiply the fractions until they have common denominators and then subtract them
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.
Subtraction
subtract
subtract
The same way you would add or subtract whole numbers, leaving the denominators alone.
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.
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.
