1 answer

To find out how many cups of almonds Luis will need, we need to set up a proportion.

The proportion is:

1/8 cup almonds / 3/4 cup chocolate chips = X cups almonds / 3 cups chocolate chips

Cross-multiply and solve for X:

(1/8) * 3 = (3/4) * X

3/8 = 3/4 * X

Divide both sides by 3/4:

(3/8) / (3/4) = X

(3/8) * (4/3) = X

12/24 = X

X = 1/2 = 0.5 cups of almonds

Therefore, Luis will need 0.5 cups of almonds. The answer is C. 0.5.
