Answer :

The answer is 3 13/20

Answer: 3 13/20

Step-by-step explanation:

so since you are adding the sides you need to find the common denominator

3/4 + 1 2/5 + 1 1/2

well the least common factor between them is over 20

15/20 (3*5 and 4*5) +

28/20 (1 2/5 = 7/5 so 7*4 and 5*4) +

30/20 (1 1/2= 3/2 3*10 and 2*10)=

15+28+30=73

73/20 and since it says mixed number

3 13/20 go into it and and 13 is prime so you can’t reduce it anymore
