Answer key · Set B
Lengths on a line plot
11 1/2 inches The leaf passes 1 and stops at the half mark before 2. That is 1 and a half inches.
23/4 The dot is 3 fourths of the way to 1, so the ribbon is 3/4 inch long.
31 5/8 inches The dot is 5 steps past 1, and each step is 1/8 inch. So the twig is 1 and 5/8 inches.
42 3/4 inches The dot is past 2. Count the fourths past 2: 1, 2, 3. So it is 2 and 3 fourths inches.
54 Count the X marks in the 1 row: there are 4.
63 Add the X marks above 1: 2 pencils of 1/2 inch and 1 pencil of 3/4 inch make 3.
71 The longest is 1 1/2 inches and the shortest is 1/2 inch. 1 1/2 − 1/2 = 1 inch.
8True There are 2 X marks over 1/2 and only 1 over 1 1/2.
92 1/2 inches 1 1/4 + 1 1/4 = 2 2/4, and 2/4 is 1/2, so the line is 2 1/2 inches.
101/2 Both leaves are 1 and some fourths. 3 fourths take away 1 fourth is 2 fourths, which is 1/2.
111-B, 2-A, 3-D, 4-C
124, 1, 3, 2 5/8 is less than 1. Then 1 1/4 is 1 2/8, 1 3/8 is next and 1 1/2 is 1 4/8.
