Step-by-step explanation:

Since 1 cup of rice is added to 2 3/4 water

We are to determine the Amount of water to be to 2 1/2 cups of rice

Let the unknown number for water be x

So let's solve

1 cup of rice=11/4 water

5/2 cup of rice=x water

Cross multiply

x=5/2×11/4

x=55/8

X=6 7/8

Therefore,6 7/8 water is needed
