To find the number of cups of almonds needed, we can set up a proportion:
18 cups of almonds / 34 cups of chocolate chips = x cups of almonds / 3 cups of chocolate chips
Cross multiply:
34 cups of chocolate chips * x cups of almonds = 18 cups of almonds * 3 cups of chocolate chips
34x = 54
Divide both sides by 34:
x = 54/34
x ≈ 1.588
Rounded to the nearest tenth, Luis will need approximately 1.6 cups of almonds.
