2.25 cups of rice is needed for a cup of water
From the question, we are told that a rice dish requires 1/3 cups of rice for every 3/4 cups of water. This can be expressed as:
1/3 cups of rice = 3/4 cups of water
For a cup of water;
x = 1 cup of water
Divide both expressions
1/3x = 3/4
Cross multiply
9x = 4
x = 9/4
x = 2.25
Hence 2.25 cups of rice is needed for a cup of water
