A. 8
B. 1/8
C. 0.25
D. 7 2/15

ANS: A
Module: Basic Math
Topic: Introduction to Fractions

Feedback
An integer is a number without any fractions or decimals. The number 8 is an
integer. The other choices contain either a fraction or a decimal.

2. The chef cuts pizzas into slices. Which fraction of a pizza has pieces that are the smallest in
size?
A. 1/4
B. 1/8
C. 1/10
D. 1/16

ANS: D
Module: Basic Math
Topic: Introduction to Fractions

Feedback
With fractions, the larger the denominator, the smaller the size of the pieces of the
whole. The pieces of a pizza that are smallest in size would be 1/16. The other
fractions represent larger pieces of the whole.

3. Which fraction is the smallest reduction of the number 24/36?
A. 1/2
B. 2/3
C. 3/6
D. 12/18

Module 1: Basic Math

To reduce a fraction, find the largest number that will divide evenly into both the
numerator and the denominator. For the fraction 24/36, the largest number is 12.
When 12 is divided into the numerator, 24 is reduced to 2. When 12 is divided into
the denominator, 36 is reduced to 3. The fraction is then 2/3. The smallest reduction
of the number 24/36 is 2/3.

4. Which number is equivalent to the improper fraction 48/10?
A. 1 19/5
B. 2 24/5
C. 3 16/3
D. 4 4/5

ANS: D
Module: Basic Math
Topic: Introduction to Fractions

Feedback
To convert an improper fraction, divide the numerator by the denominator or 48
divided by 10 = 4 with the remainder of 8. The whole number is 4 and the fractional
remainder is 8/10. Then when reducing the fraction by 2, the fraction is now 4/5.
The improper fraction of 48/10 is equal to 4 4/5.

5. Which improper fraction is equivalent to the mixed number 5 1/7?
A. 35/8
B. 36/7
C. 40/12
D. 41/13

ANS: B
Module: Basic Math
Topic: Introduction to Fractions

Feedback
To convert a mixed number to an improper fraction, multiply the denominator of the
fraction by the whole number or 5 x 7 = 35. Then add this number to the numerator
of the fraction or 35 + 1 = 36. The denominator will stay the same. The improper
fraction for the mixed number 5 1/7 is 36/7.

6. Which number would be the common denominator for the fractions 6/7 and 3/4?
A. 11
B. 20
C. 22
D. 28

,DC360 3e Instructor Test Bank 3
Module 1: Basic Math

ANS: D
Module: Basic Math
Topic: Calculations with Fractions

Feedback
When two fractions have unlike denominators, a common denominator needs to be
determined. For the fractions 6/7 and 3/4, the common denominator is 28 and is
found by multiplying the two denominators or 7 x 4 = 28.

7. What is the answer for the problem 5/3 + 7/9?
A. 2 4/9
B. 2 7/11
C. 3 5/7
D. 3 11/13

ANS: A
Module: Basic Math
Topic: Calculations with Fractions

Feedback
First, calculate the common denominator, which would be 3 x 9 = 27. Then,
calculate the first fraction by multiplying the numerator by the denominator of the
second fraction or 5 x 9 = 45. The first fraction is 45/27. The second numerator is
determined by multiplying it by the first denominator or 7 x 3 = 21. The second
fraction is 21/27. Now solve the equation 45/27 + 21/27 = 66/27. This is an
improper fraction that can be reduced by dividing 27 into 66 or 2 12/27. The fraction
12/27 can be further reduced by dividing both the numerator and denominator by the
number 3. The reduced fraction is now 4/9. The total number is 2 4/9.

8. What is the answer for the problem 11/17 – 3/5?
A. 5/23
B. 17/37
C. 7/51
D. 4/85

ANS: D
Module: Basic Math
Topic: Calculations with Fractions

Feedback
First, calculate the common denominator, which would be 17 x 5 = 85. Then,
calculate the equivalent fractions: 11 x 5 = 55 and 3 x 17 = 51. The new equation
would be 55/85 – 51/85 = 4/85.

9. What is the answer for the problem 3 4/9 x 4/11?
A. 1 25/99
B. 2 11/17
C. 3 5/19
D. 4 23/102

ANS: A
Module: Basic Math
Topic: Calculations with Fractions

Feedback
First, convert the mixed number to an improper fraction or 3 x 9 = 27. Then, add the
nominator to the total or 27 + 4 = 31/9. Now the fractions can be multiplied or 31 x
4 = 124 and 9 x 11 = 99. The answer is 124/99. When reducing this fraction, the
answer is 1 25/99. The fraction 25/99 is the lowest form.

10. What is the answer for the problem 3 7/9 ÷ 2/3?
A. 3 7/8
B. 4 5/9
C. 5 2/3
D. 6 4/11

ANS: C
Module: Basic Math
Topic: Calculations with Fractions

Feedback
First, convert the mixed number to an improper fraction or 3 x 9 = 27. Then, add the
nominator to the total or 27 + 7 = 34/9. Now the fractions can be divided by
inverting the second fraction or 34/9 x 3/2 = 102/18. When reducing to the lowest
terms, the answer is 5 12/18. With further reduction, the answer is 5 2/3.

11. Which decimal number is written correctly?
A. 0.4
B. 0.40
C. .040
D. .0400
