Question

Arnie decides to make 3 cups of dark orange paint and 3 cups of light orange paint.

Answer 1

The question is an illustration of equivalent ratios.

• 3 cups of dark orange require 3 ounces of yellow  paint
• 3 cups of light orange require 19.5 ounces of yellow paint

1 cup of dark orange requires

$Red = 7oz$

$Yellow =1oz$

To make 3 cups, we simply multiply by 3, because $3 \times 1 = 3$

So, we have:

$Red = 7oz \times 3 = 21oz$

$Yellow =1oz \times 3 = 3oz$

2 cups of light orange require

$Red =3oz$

$Yellow =13$

To make 3 cups, we simply multiply by 1.5, because $2 \times 1.5 = 3$

So, we have:

$Red = 3oz \times 1.5 = 4.5oz$

$Yellow = 13oz \times 1.5 = 19.5oz$

Hence:

• 3 cups of dark orange require 3 ounces of yellow  paint
• 3 cups of light orange require 19.5 ounces of yellow paint
