Question

Jacoby followed a recipe that requires 2 cups of water for every 3 cups of four. If he used 8 cups of four, how many cups of water did he use?

Answer 1

$\text{Jacoby followed a recipe that requires 2 cups of water for every 3 cups of flour}.\\ \text{We need to find the number of cups of water used if he used 8 cups of flour}\\ \text{so we use unitary method to find the number of cups.}\\ \\ \text{for 3 cups of flour, the number of cups of water needed}=2\\ \\ \text{so for 1 cup of flour, the number of cups of water needed}=\frac{2}{3}$

$\text{Hence for 8 cup of flour, the number of cups of water needed}=\frac{2}{3}\times 8\\ \\ =\frac{16}{3} \text{ cups of water}$

Hence the number of cups of water he will use is: 16/3 cups of water
