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