Which expression is equal to -0.4(3/2-1/4)? A. -3/8-1/16
B. -3/8+1/16
C. -3/5-1/10
D. -3/5+1/10

The answer is D.

Step-by-step explanation:

The answer is D because the result of the -0.4(3/2-1/4) is -1/2 or -0.5. I checked the answers for everyone, they didn't match except for D, which result also ended in -0.5. You could also open parenthesis and solve like that but I like to compare and double check with the results.

Hope this helped!!
