JoJo has 1 1/2 cups of sugar. She used 3/4 cup for her cookies. How much does she have left?

Question

A. 3/4 cup
B. 1 1/4 cups
C. 2/4 cup
D. 2 1/4 cup

Answer 1

To determine how much sugar JoJo has left, we need to subtract the amount of sugar she used from the total amount she initially had. Let's perform the subtraction:

1. Start with the initial amount of sugar:
$1\frac{1}{2}$ cups

2. Convert the mixed number to an improper fraction:
$1\frac{1}{2}=\frac{3}{2}$ (since $1\frac{1}{2}=1+\frac{1}{2}=\frac{2}{2}+\frac{1}{2}=\frac{3}{2}$)

3. Subtract the amount of sugar used, which is $\frac{3}{4}$:

First, find a common denominator for the fractions $\frac{3}{2}$ and $\frac{3}{4}$. The common denominator is 4.

Convert $\frac{3}{2}$ to a fraction with denominator 4:
$$\frac{3}{2}=\frac{3\times 2}{2\times 2}=\frac{6}{4}$$

Now we subtract:
$$\frac{6}{4}-\frac{3}{4}=\frac{6-3}{4}=\frac{3}{4}$$

So, JoJo has $\frac{3}{4}$ cup of sugar left.

Thus, the correct answer is:
**A. 3/4 cup**
