The graph shows the number of erasers 3 pupils collected. Study the graph and answer the following.
- Who collected 10 erasers? Give the answer in number. (Eg 1)
- Which 2 pupils collected a total of 26 erasers? Give the answer in numbers. (Eg 1, 2)
- How many erasers must Molly give to Julie so that both of them would have the same number of erasers?
(a)
2 erasers → 1 box
10 erasers → 10 ÷ 2 = 5 boxes
(3) Julie has 5 boxes so she collected 10 erasers.
(b)
Total number of boxes represented by 26 erasers
= 26 ÷ 2
= 13
Number of boxes that Elsa and Julie had
= 8 + 5
= 13
2 pupils who collected a total of 26 erasers are (1) Elsa and (3) Julie.
(c)
Difference in the number of boxes between Molly and Julie
= 6 - 5
= 1
Number of erasers that Molly must give to Julie
= 1 ÷ 2 x 2
= 1
Answer(s): (a) 3; (b) 1, 3; (c) 1
