Answer 1

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.

Answer 2

was that correct

Answer 3

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!
