CHAPTER 1



1. When working with fractions, what is the term for the greatest common number that divides evenly into both the
numerator and the denominator?

1. Divisor
2. Factor
3. Dividend
4. Product


ANSWER: 2
Rationale: The greatest common number, or factor, is one that divides evenly into both the numerator and the denominator.




2. When adding fractions with different denominators, the fractions must be changed to have a common denominator.
What is the term for this change?

1. Transforming
2. Averaging
3. Lowering
4. Raising


ANSWER: 4
Rationale: Adding fractions with different denominators involve “raising” fractions to higher
terms to have a common denominator.




3. Reducing a fraction to the lowest terms involves which of the following?
1. Finding a factor that divides evenly into both the numerator and denominator

2. Finding a common denominator for the fractions and adding the numerators
3. Finding a common denominator for the fractions and subtracting the smaller fraction from the larger one
4. Multiplying the numerators and denominators of the fractions


ANSWER: 1
Rationale: Reducing a fraction to the lowest terms involves finding a factor that divides evenly into both the numerator and
denominator. (2) refers to adding fractions, (3) refers to subtracting fractions, and (4) refers to multiplying fractions.

4. Which statements are true when discussing improper fractions? Select all that apply.
1. Numerators are greater than or equal to their denominators.
2. Improper fractions contain both a whole number and a fraction.
3. The value of an improper fraction is greater than or equal to one.
4. Numerators are less than their denominators.
5. Improper fractions contain a numerator and denominator that are both divisible by the number two.


ANSWER: 1, 3
Rationale: Improper fractions have numerators that are greater than or equal to their denominators. The value of an improper
fraction is equal to or greater than one. Mixed fractions contain both a whole number and a fraction. Proper fractions have
numerators that are less than their denominators. Divisibility by two does not affect whether a fraction is proper or improper.




5. Which of the following operations requires finding a common denominator before completing the equation? Select
all that apply.

1. Adding fractions
2. Subtracting fractions
3. Multiplying fractions
4. Dividing fractions
5. Reducing reactions


ANSWER: 1, 2
Rationale: Adding fractions requires finding a common denominator for the fractions, adding the numerators, and then
reducing the result to the lowest terms. Subtracting fractions requires finding a common denominator for the fractions,
subtracting the smaller fraction from the larger one, and then reducing the result to the lowest terms. The other options do no
require finding a common denominator.




6. Which of the following is true regarding mixed fractions?
1. The numerator is always greater than the denominator.
2. The value is always less than one.
