Question

Jessica and dewanda each created a cleaning solution using bleach and water. Jessica added 2/3 cup of bleach to every 2 gallons of water. Dewanda added 1/2 cup of bleach to every gallon of water. Who created a stronger bleach cleaning solution?

Answer 1

Dewanda created the stronger bleach cleaning solution

To know who created a stronger bleach cleaning solution, we need to compare the ratio of bleach to water for each solution produced.

For Jessica:

• 2/3 cups of bleach = 2 gallons of water

For 1 cup of water , we'll have

2/3 = 2

x = 1

cross multiply

2x = 2/3

x = 2/3 × 1/2

x = 2/6 = 1/3

For Dewanda :

• 1/2 cups = 1 gallon of water

Comparing the ratios

1/2 > 1/3

Hence, Dewanda created the stronger solution.
