Below are sample questions representative of the exercises included on this worksheet and related 3.64 Unit Fractions on a Number Line skill assessments:

Problem 1Difficulty: Mastery
A final label card must include both the point value and the denominator from the partitions. Which card is correct for the number line shown?
APoint R = 1/12; denominator 12
BPoint R = 1/11; denominator 11
CPoint R = 2/12; denominator 12
DPoint R = 12/1; denominator 12
Solution & Explanation:The number line has 12 equal spaces, and point R is at the first tick mark after 0. The point value is 1/12 and the denominator is 12.
Problem 2Difficulty: Mastery
Which choice best evaluates this statement? On a number line divided into 3 equal spaces, the first tick mark after 0 is 1/4 because four tick marks are shown.
ACorrect: 4 tick marks mean the denominator is 4
BIncorrect: 3 equal spaces mean the first tick mark is 1/3
CIncorrect: the first tick mark is 2/3 because 0 is counted
DCorrect: the first tick mark is 1/4 on every 3-space line
Solution & Explanation:Four tick marks including endpoints make 3 equal spaces. The denominator counts spaces, so the first tick mark is 1/3.
Problem 3Difficulty: Mastery
Which true statement can be made about the point at the first tick mark on the number line shown?
AIt represents 1/7 because there are 7 equal spaces
BIt represents 1/8 because there are 8 tick marks including endpoints
CIt represents 2/7 because the first mark is after 0
DIt represents 7/1 because 7 equal spaces make the whole
Solution & Explanation:There are 7 equal spaces from 0 to 1. A point at the first tick mark is one of those 7 spaces, so it represents 1/7.
