The graph shows the number of coins 3 pupils collected. Study the graph and answer the following.
- Who collected 56 coins? Give the answer in number. (Eg 1)
- Which 2 pupils collected a total of 104 coins? Give the answer in numbers. (Eg 1, 2)
- How many coins must Jane give to Ava so that both of them would have the same number of coins?
(a)
8 coins → 1 triangle
56 coins → 56 ÷ 8 = 7 triangles
(2) May has 7 triangles so she collected 56 coins.
(b)
Total number of triangles represented by 104 coins
= 104 ÷ 8
= 13
Number of triangles that May and Ava had
= 7 + 6
= 13
2 pupils who collected a total of 104 coins are (2) May and (3) Ava.
(c)
Difference in the number of triangles that Jane and Ava had
= 8 - 6
= 2
Number of coins that Jane must give to Ava
= 2 ÷ 2 x 8
= 8
Answer(s): (a) 2; (b) 2, 3; (c) 8
