2. A temperature of 104° F converts to a Celsius temperature of:
a. 40° C
b. 75.6° C
c. 129.6° C
d. 72° C
ANS: A
Feedback
A 104 – 32 = 72
72 5 = 360
360/9 = 40
B This answer (75.6° C) is the result of adding 32 to the Fahrenheit temperature
instead of subtracting it.
C This answer (129.6° C) is the result of multiplying by 9/5 instead of 5/9.
D This answer (72° C) is the result of subtracting 32 from the Fahrenheit
temperature without multiplying by the fraction 5/9.

a. 12
b. 6
c. 5
d. 24
ANS: A
Feedback
A The smallest number that is divisible by all three denominators (3, 2, 4) is 12.
B Four does not divide evenly into 6.
C None of the denominators divide evenly into 5.
D Although all of the denominators divide evenly into 24, it is not the smallest
common denominator.

a. 30
b. 3.00
c. 0.1875
d. 0.50
ANS: B
Feedback
A This answer is the result of dividing 0.75 by 0.025.
B After moving the decimal places over two positions in the divisor and the
dividend, then proceeding with division, the result is the whole number 3.
C This is the product of the two numbers, not the quotient.

6. Eighteen is 30% of:
a. 540
b. 60
c. 0.06
d. 54
ANS: B
Feedback
A This answer (540) is the result of multiplying 18 by 30. (This is not the correct
way to determine percentage.)
B 18 = 30%x
18 = 0.30x
18/0.30 = x
18/0.30 = 60
C This answer (0.06) is the result of dividing 0.018 by 0.30. (This eliminates the
step of moving the decimal to the right to create a divisor that is a whole
number.)
D This answer (54) is the result of multiplying 18 by 3 instead of dividing by 0.30.

a. 120,000
b. –40
c. 3
d. 2.08
ANS: C
Feedback
A This answer (120,000) is the result of multiplying the two terms on the right
(500, 600) and dividing by the numeric term on the left (2.5).
B This answer (–40) is the result of subtracting the two terms on the right (500,
600) and dividing by the numeric term on the left (2.5).
C This answer (3) is the result of multiplying the means and the extremes and then
dividing to find the unknown.
D This answer (2.08) is the result of multiplying an extreme (2.5) by a mean (500)
and dividing by the other extreme (600).
