Hello from MrBillDoesMath!
Answer:
Choices 1, 2, and 4 are correct.
Discussion:
1 7/8 + 2 3/8 =
1 + 2 + ( 7/8 + 3/8) =
1 + 2 + 10/8 =
3 + (1 + 2/8) =
4 1/4
The first choice in the top row is precisely that value. (It is correct)
The second row is also correct as 34/8 = 17/4 = 4 1/4
The third choice is incorrect as the sum shown (4/8) = 1/2 not 4 1/4
The fourth choice is correct as 4 2/8 = 4 1/4
The fifth choice is incorrect as 3 21/8 = 3 + 2 + 5/8 <> 4 1/4
