The graph shows the number of postcards 3 pupils collected. Study the graph and answer the following.
- Who collected 32 postcards? Give the answer in number. (Eg 1)
- Which 2 pupils collected a total of 80 postcards? Give the answer in numbers. (Eg 1, 2)
- How many postcards must Candy give to Penny so that both of them would have the same number of postcards?
(a)
8 postcards → 1 box
32 postcards → 32 ÷ 8 = 4 boxes
(1) Molly has 4 boxes so she collected 32 postcards.
(b)
Total number of boxes represented by 80 postcards
= 80 ÷ 8
= 10
Number of boxes that Molly and Candy had
= 4 + 6
= 10
2 pupils who collected a total of 80 postcards are (1) Molly and (3) Candy.
(c)
Difference in the number of boxes between Candy and Penny
= 6 - 5
= 1
Number of postcards that Candy must give to Penny
= 1 ÷ 2 x 8
= 4
Answer(s): (a) 1; (b) 1, 3; (c) 4
