Question

ada is making rice. the instructions call for $2\frac{1}{4}$ cups of water for 1 cup of rice. ada is using only $\frac{1}{3}$ cup of rice. make a prediction about the amount of water ada needs. ada needs ? $2\frac{1}{4}$ cups of water.

Explanation:

Step1: Convert mixed number to fraction

$2\frac{1}{4} = \frac{9}{4}$

Step2: Multiply by rice amount

$\frac{9}{4} \times \frac{1}{3} = \frac{9}{12} = \frac{3}{4}$

Step3: Compare to original water amount

$\frac{3}{4}$ is less than $2\frac{1}{4}$

Answer:

Ada needs $\frac{3}{4}$ cups of water, which is less than $2\frac{1}{4}$ cups of water.
