To find out how much sugar oJo has left, we need to subtract the amount of sugar she used for her cookies from the total amount she had.
oJo started with:
1 1/2 cups of sugar = \( \frac{3}{2} \) cups
She used:
3/4 cup of sugar = \( \frac{3}{4} \) cups
Now, we subtract:
\[
\frac{3}{2} - \frac{3}{4}
\]
To do this, we need a common denominator. The least common multiple of 2 and 4 is 4.
Now, converting \( \frac{3}{2} \) to a fraction with a denominator of 4:
\[
\frac{3}{2} = \frac{3 \times 2}{2 \times 2} = \frac{6}{4}
\]
Now we can perform the subtraction:
\[
\frac{6}{4} - \frac{3}{4} = \frac{6 - 3}{4} = \frac{3}{4}
\]
So, oJo has \( \frac{3}{4} \) cup of sugar left.
The correct response is **3 fourths cup**.
