  • 48 pints

  • 24 pints

  • 96 pints

  • 56 pints

Correct answer: 48 pints

There are 4 quarts in one gallon, and 2 pints in one quart; therefore, there are 8 pints in one gallon. Use a conversion fraction to solve for x, the unknown number of pints in 6 gallons:

x/6 = 8/1

Cross multiply: x = 6 x 8

x = 48

48 pints of blood were collected.

Ninety patients are enrolled in a clinical trial. One of every six patients smokes cigarettes. How many non-smokers are enrolled in the clinical trial?

  • 75

  • 15

  • 60

  • 45

Correct answer: 75

This problem can be solved using ratios. Since one in six patients smokes, five in six patients do not; therefore, the ratio used to solve the problem is 5:6. x is used in the following equation to represent the unknown number of non-smokers out of the total of 90 enrolled patients.

5/6 = x/90

Cross multiply: 6x = 5 × 90

6x = 450

x = 450/6

x = 75

Seventy-five non-smokers are enrolled in the clinical trial.
