Question

Angela had 2 cups of flour. She used 1 1/4 cups when making muffins. Angela says she has 3/4 cup of flour left.

Is Angela's answer reasonable?

Answer 1

Angela's answer is reasonable because if you had 2, and you subtracted 1 and 1/4, you would be left with 3/4 left. You can easily check your work by doing
3/4 + 1 1/4 = 2
