Answer:
Brooke put the value 12 into the cups of juice, and not the cups of sugar. She was searching for how many cups of sugar she needs, not juice.
Explanation:
2/3 = ?/12.
This is how the equation is supposed to be. Then you solve it from there.
Do cross multiplication.
24 = 3x
Divide by 3 on both sides.
x = 8.
She needs 8 cups of juice.
Also, I hope everything goes well at school! Good luck :)
