Ok I hate fractions I am trying to help my son do this and as far as I can tell what the answer is does not sound right here is the problem I did u-tube and it just does not seem right??

5/5*(4/4-3/3) I come up with 0/60 how can that be right what am I doing wrong?

Order of operations says do (4/4 - 3/3) first. Get them in LCD, so 4/4 is the same as 12/12 and 3/3 is the same as 12/12. 12/12 - 12/12 equals 0. 5(0) equals zero.

5/4ths of people have a problem with fractions.

LOL love the answers.
if you really still need an answer with your work, i'm sure the problem says something like solve for in fraction term, do not simplify, which mean you cant simply convert 4/4 and 3/3 and 5/5 to 1.
to subtract 4/4-3/3 you need to have like denominator. so 4*3=12. Denominator will be 12. so your fractions are 12/12-12/12. You only subtract the numerator. (the answer is NOT 0/0) your answer in fraction form is 0/12.

Then multiply 5/5(0/12) you multiply numerators and denominators together.
5x0=0 and 5x12=60. Correct answer is 0/60

Thats how you get 0/60 and not just 0. The answer is different. 0 is simplified and 0/60 is not.
