Question

To mix weed killer with water correctly it is necessary to mix 6 teaspoons of weed killer with 2 gallons of water. Find how many gallons of water are needed to mix with the entire box if it contains 12 teaspoons of weed killer

Answer 1

The correct proportion for mixing weedkiller with water is;

$6\text{tsp:}2\text{gal}$

When the entire box contains 12 teaspoons of weedkiller, we would now have;

$\begin{gathered} \frac{6}{2}=\frac{12}{x} \\ \text{Where;} \\ x=\text{gallons of water} \\ \text{Cross multiply and we'll have;} \\ x=\frac{12\times2}{6} \\ x=4 \end{gathered}$

ANSWER:

To mix 12 teaspoons of weedkiller, 4 gallons of water is needed.
