The graph shows the number of cards 3 pupils collected. Study the graph and answer the following.
- Who collected 49 cards? Give the answer in number. (Eg 1)
- Which 2 pupils collected a total of 91 cards? Give the answer in numbers. (Eg 1, 2)
- How many cards must Ella give to Jen so that both of them would have the same number of cards?
(a)
7 cards → 1 triangle
49 cards → 49 ÷ 7 = 7 triangles
(2) Zoe has 7 triangles so she collected 49 cards.
(b)
Total number of triangles represented by 91 cards
= 91 ÷ 7
= 13
Number of triangles that Zoe and Jen had
= 7 + 6
= 13
2 pupils who collected a total of 91 cards are (2) Zoe and (3) Jen.
(c)
Difference in the number of triangles that Ella and Jen had
= 8 - 6
= 2
Number of cards that Ella must give to Jen
= 2 ÷ 2 x 7
= 7
Answer(s): (a) 2; (b) 2, 3; (c) 7
