Question

Molly has cups of sugar. She used cup of sugar. She wants to model a subtraction problem on a number line to find how much sugar she has left. Molly’s first step is shown below.
What should Molly do next, and how much sugar does she have left?
A. Move units to the right. She has cups of sugar left.

B. Move unit to the left. She has cup of sugar left.

C. Move units to the left. She has cup of sugar left.

D. Move unit to the right. She has cups of sugar left.

Answer 1

I am going off the assumption that by "She used a cup of sugar" you mean that she used 1 cup of sugar. Since the model shows that her first step starts with 1.5, that means that she loses 1 cup, and moves 1 unit to the left. She is left with 0.5 cups of sugar.
B. She only moves 1 unit to the left.

It was 1 1/2 and 3/4 cups
