Given:
Linda mixes rice and water in a ratio of 3: 5.
She uses 30 cups of rice
Using the ratio and proportions:
Rice : Water
3 : 5
30 : x
So, if the number of cubs of water = x
the value of x will be calculated as follows using cross multiplication:
[tex]x=\frac{30\times5}{3}=10\times5=50[/tex]so, the answer will be:
She needs 50 cups of water.
