Answer 1

To find out how many cups of almonds Luis needs when he uses 3 cups of chocolate chips, we can set up a proportion based on the recipe.

The recipe states that for every 3/4 cup of chocolate chips, Luis needs 1/8 cup of almonds. We can express this as a ratio:

\[
\frac{1/8 \text{ cup almonds}}{3/4 \text{ cup chocolate chips}}
\]

Next, to find out how many cups of almonds he needs for 3 cups of chocolate chips, we can set up the equation:

\[
\frac{1/8}{3/4} = \frac{x}{3}
\]

Cross-multiplying gives:

\[
(1/8) * 3 = (3/4) * x
\]

Calculating the left side:

\[
3/8 = (3/4) * x
\]

Now, to solve for \(x\), we can multiply both sides by \(4/3\):

\[
x = (3/8) * (4/3)
\]

Calculating the right side:

\[
x = 1/2
\]

Thus, Luis will need **0.5 cups** of almonds when he uses 3 cups of chocolate chips.

The answer is **0.5 cup**.
