Answer 2

The three choices that are greater than 3 are:

A 1 3/4 + 1 1/5

C 1 7/8 + 2/5

D 1 7/8 + 1 1/4

Answer 3

I apologize for the incorrect response. Let's simplify each expression to find the three choices that are greater than 3.

A 1 3/4 + 1 1/5 = 1 + 3/4 + 1 + 1/5 = 2 + 1 3/4 + 1/5 = 3 3/4 + 1/5 = (3 + 3 + 1) + (4/4 + 1/5) = 7 + 9/20 = 7 9/20

B 2 + 1 1/5 = 2 + 1 + 1/5 = 3 + 1/5 = 3 + 1/5 = 3 1/5

C 1 7/8 + 2/5 = 1 + 7/8 + 2/5 = 1 + 35/40 + 16/40 = 1 + 51/40 = (1 + 1 + 10/40) + 11/40 = 2 + 21/40 = 2 21/40

D 1 7/8 + 1 1/4 = 1 + 7/8 + 1 + 1/4 = 1 + 28/32 + 4/32 = 1 + 32/32 + 4/32 = (1 + 1 + 4/32) + 4/32 = 2 + 8/32 = 2 + 1/4 = 2 1/4

So, the three choices that are greater than 3 are:

A 7 9/20
C 2 21/40
D 2 1/4
