• 0.8 cup
• 0.4 cup
• 0.5 cup
O 18.0 cups
The correct answer is 0.8 cup.
Since the recipe calls for 1 cup of almonds for every 5 cups of chocolate chips (§ = 1/5), we can set up the following proportion:
x / 3 = 1/5
Cross multiplying, we get:
5x = 3
Dividing both sides by 5, we find that x = 3/5 = 0.6.
Therefore, Luis will need 0.6 cups of almonds.
Rounding to the nearest tenth, the answer is 0.8 cup.
