The graph shows the number of cards 3 students collected. Study the graph and answer the following.
- Who collected 10 cards? Give the answer in number. (Eg 1)
- Which 2 students collected a total of 26 cards? Give the answer in numbers. (Eg 1, 2)
- How many cards must Mia give to Sonia so that both of them would have the same number of cards?
(a)
2 cards → 1 box
10 cards → 10 ÷ 2 = 5 boxes
(3) Sonia has 5 boxes so she collected 10 cards.
(b)
Total number of boxes represented by 26 cards
= 26 ÷ 2
= 13
Number of boxes that Molly and Sonia had
= 8 + 5
= 13
2 students who collected a total of 26 cards are (1) Molly and (3) Sonia.
(c)
Difference in the number of boxes between Mia and Sonia
= 6 - 5
= 1
Number of cards that Mia must give to Sonia
= 1 ÷ 2 x 2
= 1
Answer(s): (a) 3; (b) 1, 3; (c) 1
