To find out how much sugar JoJo has left after using some for her cookies, we start with the amount she had and subtract the amount she used.
1. **Convert 1 1/2 cups to an improper fraction**:
\[
1 \frac{1}{2} = \frac{3}{2}
\]
2. **Convert 3/4 cup to a fraction with a common denominator**:
The common denominator for 2 and 4 is 4.
\[
\frac{3}{2} = \frac{3 \times 2}{2 \times 2} = \frac{6}{4}
\]
So, 1 1/2 cups is the same as 6/4 cups.
3. **Subtract the amount used**:
\[
\frac{6}{4} - \frac{3}{4} = \frac{6 - 3}{4} = \frac{3}{4}
\]
Thus, JoJo has **3/4** cups of sugar left.
The correct response is:
**3/4**.

Yes, that calculation is correct!
JoJo started with \(1 \frac{1}{2}\) cups of sugar, which is \( \frac{3}{2} \) or \( \frac{6}{4} \) when converted to a fraction with a common denominator. After using \( \frac{3}{4} \) cup for her cookies, the subtraction gives:
\[
\frac{6}{4} - \frac{3}{4} = \frac{3}{4}
\]
So, she has \( \frac{3}{4} \) cups of sugar left. Therefore, the answer **3/4** is indeed correct!
