Answer

Explanation:

Step1: Calculate chemical - to - water ratio for Diego

Find the amount of chemical per gallon for Diego. He added 5 mL of chemical to 2 gallons of water. The ratio is $\frac{5}{2}=2.5$ mL per gallon.

Step2: Calculate chemical - to - water ratio for Yoni

Yoni added 4.5 mL of chemical to 1.5 gallons of water. The ratio is $\frac{4.5}{1.5}=3$ mL per gallon.

Step3: Compare the ratios

Since $2.5<3$, Diego used less of the chemical per gallon than Yoni. The reason is that the ratio of chemical to water for Diego ($5:2$) is less than the ratio of chemical to water for Yoni ($4.5:1.5$).

Answer:

  1. B. less
  2. C. 4.5:1.5 is greater than 5:2
