The graph shows the number of erasers 3 pupils collected. Study the graph and answer the following.
- Who collected 56 erasers? Give the answer in number. (Eg 1)
- Which 2 pupils collected a total of 96 erasers? Give the answer in numbers. (Eg 1, 2)
- How many erasers must Vina give to Ava so that both of them would have the same number of erasers?
(a)
8 erasers → 1 circle
56 erasers → 56 ÷ 8 = 7 circles
(2) Jen had 7 circles so she collected 56 erasers.
(b)
Total number of circles represented by 96 erasers
= 96 ÷ 8
= 12
Number of circles that Ava and Jen had
= 7 + 5
= 12
2 pupils who collected a total of 96 erasers are (2) Jen and (3) Ava.
(c)
Difference in the number of circles between Vina and Ava
= 6 - 5
= 1
Number of erasers that Vina must give to Ava
= 1 ÷ 2 x 8
= 4
Answer(s): (a) 2; (b) 2, 3; (c) 4
