The graph shows the number of erasers 3 pupils collected. Study the graph and answer the following.
- Who collected 14 erasers? Give the answer in number. (Eg 1)
- Which 2 pupils collected a total of 24 erasers? Give the answer in numbers. (Eg 1, 2)
- How many erasers must Lily give to Aria so that both of them would have the same number of erasers?
(a)
2 erasers → 1 circle
14 erasers → 14 ÷ 2 = 7 circles
(2) Kitty had 7 circles so she collected 14 erasers.
(b)
Total number of circles represented by 24 erasers
= 24 ÷ 2
= 12
Number of circles that Aria and Kitty had
= 7 + 5
= 12
2 pupils who collected a total of 24 erasers are (2) Kitty and (3) Aria.
(c)
Difference in the number of circles between Lily and Aria
= 6 - 5
= 1
Number of erasers that Lily must give to Aria
= 1 ÷ 2 x 2
= 1
Answer(s): (a) 2; (b) 2, 3; (c) 1
