How do you make 4/3 and 3/3 have a denominator of 5

Step-by-step explanation:

Actually, you can't.  You could multiply the numerator and denominator of each 4/3 and 3/3 by 5, obtaining:

5(4)          5(3)

and

5(3)           5(3)

but this result has little practical value.  4/3 and 3/3 could be combined immediately, obtaining 7/3, if that's what you want to do, as the fractions already have the same denominator (3).
