Evaluate: -3/4 - 1 3/8

A: - 17/8 B: -1

C: 17/8 D: -5/8

I put C but its was incorrect. I'm to sure what the correct answer would then be. can you show me how to solve it and how to achieve the correct answer?

-3/4 = -6/8

-6/8 - 11/8 = -17/8 = -2 1/8
You were actually pretty close, April.

During the solving of this problem, the answer turns into a negative because of the negative 3/4. So, it is actually A, and not C.

-3/4 - 1 3/8

Subtract the fractions by converting them into decimals, and leaving the 1 out.

-0.75 - 0.375 = -1.125

Then, you subtract 1 from -1.125.

-1.125 - 1 = -2.125

I hope this helps you understand your mistake! :)
Ms. Sue is correct as well.

I forgot to mention:

-2.125 = -17/8
