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. options: more than, less than

Explanation:

Step1: Analyze the ratio

For 1 cup of rice, water needed is $2\frac{1}{4}$ cups. Now, Ada is using $\frac{1}{3}$ cup of rice, which is less than 1 cup.

Step2: Determine the water amount

Since the amount of rice is less than 1 cup, the amount of water needed should be less than the water needed for 1 cup of rice (which is $2\frac{1}{4}$ cups). So we compare the water needed for $\frac{1}{3}$ cup of rice with $2\frac{1}{4}$ cups. The water needed for $\frac{1}{3}$ cup of rice is $2\frac{1}{4}\times\frac{1}{3}=\frac{9}{4}\times\frac{1}{3}=\frac{3}{4}$ cups, and $\frac{3}{4}<2\frac{1}{4}$.

Answer:

less than
