Answer:
1. 5 3/4 - 2 1/4 = 3 1/12 2. 7 2/3 + 2 1/5 = 9 13/15
Step-by-step explanation:
1. 5 3/4 - 2 1/4
subtract the numbers on the side 5-2=3
subtract the fraction 3/4-1/4=2/4
reduce 2/4=1/2
add them together 3+1/2=3 1/2
2. 7 2/3 + 2 1/5
subtract the numbers on the side 7+2=9
find LCD of 2/3 and 1/5=
10/15+3/15=13/15
add them together 9+13/15=9 13/15
