Fire fighter Mathematics Exam
Questions And Answers
Change the following fraction to a percentage: 2/25 -
correct answer ✅A. 0.18%
B. 2.5%
C. 8%
D. 25%
Reasoning:
To solve the problem, multiply the fraction by 100. 2/25 = 200/25.
Then divide the fraction's bottom number into the top number. 200
÷ 25 = 8. Add the percent sign: 2/25 = 8%.
Choice C is correct
If a pile of fire wood is 6 feet long, 4 feet high and 2 feet wide how
many cubic feet is it? -
correct answer ✅A. 96 cubic feet
B. 18 cubic feet
C. 48 cubic feet
D. 46 cubic feet
Reasoning:

Questions And Answers
To calculate how many cubic feet of water can the tank hold, you
would multiply 6 x 4 x 2 = 48 cubic feet.
Answer 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 3/4 inches. What is the
width of the third layer? -
correct answer ✅A. 7/8 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 3/4 = 14/8. Add the first and second layer
and then subtract the sum from the total thickness: 4/8 + 3/8 = 7/8.
14/8 - 7/8 = 7/8 inch.
Choice A is correct
Water container A holds 150 gallons of water when full. Water
container B, holds 270 gallons of water when full. If water container
,Fire fighter Mathematics Exam
Questions And Answers
A is only 3/4 full and water container B is only 1/3 full, how many
more gallons of water are needed to fill both container to their
limit? -
correct answer ✅A. 225 gallons
B. 217.5 gallons
C. 250 gallons
D. 215.5 gallons
Reasoning:
First, you must find the number of gallons of water missing from
each container: water container A = 1/4, water container B = 2/3.
Multiply by the number of gallons each truck holds when full: water
container A = 150, 1/4 x 150 = 37.5 gallons, water container B =
270, 2/3 x 270 = 180. Now add the numbers of gallons missing to
get the number of gallons needed to fill the water containers. 37.5
+ 180 = 217.5 gallons.
Choice B is correct
One gallon of water weighs 8.5 pounds. If the water tank on a
pumper truck holds 600 gallons of water when full, how much does
the water weigh? -
correct answer ✅A. 5,100 pounds
, Fire fighter Mathematics Exam
Questions And Answers
B. 6,850 pounds
C. 662 pounds
D. 5, 350 pounds
Reasoning:
To calculate the weight of the water, multiply the volume of water
by the weight per gallon: 600 x 8.5 = 5,100 pounds.
Choice A is correct
In one year, there were about 21,500 residential fires started by
children playing with matches. Of these incidents, 11,350 children
suffered third-degree burns. About what percent of these fires
resulted in burns? -
