Question

To make a batch of rice, 20 cups of water are combined with 10 cups of rice. How many cups of water are needed for one cup of rice?​

Answer 1

2 cups of water

Explanation:

Given ratio for a batch of rice:

water : rice = 20 : 10 (cups)

Let x = cups of water needed for 1 cup of rice:

⇒ 20 : 10 = x : 1

write as fractions:

⇒ 20 / 10 = x / 1

cross multiply:

⇒ 20 × 1 = x × 10

⇒ 20 = 10x

solve for x:

⇒ x = 20/10

⇒ x = 2

Therefore, 2 cups of water are needed for 1 cup of rice.

Answer 2

2 cups of water

solving steps:

20 cups of water → 10 cups of rice

rearrange the following

10 cups of rice → 20 cups of water

divide both sides by 10

1 cup of rice → 2 cups of water
