Do you need to simplify when adding fractions?

Answer 1

YES!!!

When adding/subtracting fractions., the steps to take are

#1 ; Convert to Improper(top heavy) fractions.

#2 ; Bring to a common denominator

#3 ; Bring the numerstors (top) to the equivalent values of the denomintor.

#4 ' add/subtract the numertors

#5; Place over the denominator.

#6 ; Bring back ( simplify) to a mixed number.

e.g.

5 3/5 + 7 2/3

#1 ; 28/5 + 23/3

#2 ; 5 x 3 = 15

#3 ; 28(3) + 23(5)) / 15 = (84 + 115)

#4 ; 199

#5 ; 199/15

#6 ; 13 4/15 The answer !!!! Done (Hope that helps).

For subtraction ; subtract the numerators at step #3/#4. Otherwise proceed as above.
