B. 0.28
C. 1.56
D. 1.02
Reasoning:
To solve the problem, drop the percent sign and move the decimal point two places to the left: 56% = 0.56.
Choice A is correct
During a fire, the pump control gauge shows a pressure of 240 pounds per square inch (psi) at 2:30 p.m. By 2:45 p.m. the pressure had reduced to 90 psi. What was the average psi loss per minute?
A. 8
B. 11
C. 9
D. 10
Reasoning:
To find the average psi loss per minute, you must calculate the total amount of psi loss: 240 - 90 = 150 psi. Then, determine the length of time: 2:45 - 2:30 = 15 minutes. Next, divide the psi total by the number of minute
What is 25% of 90?
A. 19
B. 25
C. 22.5
D. 20
Reasoning:
To solve the problem 25% of 90, multiply both numbers together and divide by 100: 25 x 90 = 2,250 � 100 = 22.5.
Choice C is correct
Flooring in an older house has three layers of plywood. Each layer is a different thickness. One layer is 1/2 inch thick, a second layer is 3/8 inch thick and the total thickness is 1 1/2 inches. What is the width of the third layer?
A. 5/8 inch
B. 1/2 inch
C. 3/8 inch
D. 7/16 inch
Reasoning:
First, find the common denominator = 8. Then convert all fractions: 1/2 = 4/8, 3/8 = 3/8, 1 1/2 = 12/8. Add the first and second layer and then subtract the sum from the total thickness: 4/8 + 3/
What is 15% of 90?
A. 19
B. 35
C. 13.5
D. 45
Reasoning:
To solve the problem 15% of 90, multiply both numbers together and divide by 100: 15 x 90 = 1350 � 100 = 13.5.
Choice C is correct
In one year, there were about 512 visits paid to neighborhood schools as part of the fire education program. There are 800 schools in the district. What percentage were visited?
A. 49%
B. 51%
C. 64%
D. 57%
Reasoning:
To calculate the percentage of visits, you would first multiply 512 x 100 � 800 = 64.
Choice C is correct
During a fire, the pump control gauge shows a pressure of 360 pounds per square inch (psi) at 12:30 p.m. By 1:10 p.m. the pressure had reduced to 210 psi. What was the average psi loss per minute?
A. 3
B. 5
C. 6
D. 3.75
Reasoning:
To find the average psi loss per minute, you must calculate the total amount of psi loss: 360 - 210 = 150 psi. Then, determine the length of time: 12:30 - 1:10 = 40 minutes. Next, divide the psi total by the number of min
30% of firefighters in a mid-sized town are women. If there are 200 firefighters in the station, how many women work there?
A. 60
B. 50
C. 70
D. 30
Reasoning:
To calculate the number of female firefighters working in the station, multiply 30% or .30 x 200 = 60.
Choice A is correct
Change the following fraction to a percentage: 3/8
A. 37.5%
B. 35%
C. 40%
D. 96%
Reasoning:
To solve the problem, multiply the top fraction by 100. 3/8 = 300/8. Then divide the fraction's bottom number into the top number. 300 � 8 = 37.5. Add the percent sign: 3/8 = 37.5%.
Choice A is correct
What is 30% of 40?
A. 15
B. 10
C. 70
D. 12
Reasoning:
To solve the problem 30% of 40, multiply both numbers together and divide by 100: 30 x 40 = 1200 � 100 = 12.
Choice D is correct
70% of firefighters in a station were married. If there are 60 firefighters in the station, how many were single?
A. 18
B. 22
C. 50
D. 47
Reasoning:
To calculate the number of single firefighters working in the station, multiply 70% or .70 x 60 = 42. Since there are a total of 60 firefighters you would then subtract 60 - 42 = 18.
Choice A is correct
