The graph shows the number of buttons 3 students collected. Study the graph and answer the following.
- Who collected 28 buttons? Give the answer in number. (Eg 1)
- Which 2 students collected a total of 48 buttons? Give the answer in numbers. (Eg 1, 2)
- How many buttons must Kay give to Jen so that both of them would have the same number of buttons?
(a)
4 buttons → 1 circle
28 buttons → 28 ÷ 4 = 7 circles
(2) Kitty had 7 circles so she collected 28 buttons.
(b)
Total number of circles represented by 48 buttons
= 48 ÷ 4
= 12
Number of circles that Jen and Kitty had
= 7 + 5
= 12
2 students who collected a total of 48 buttons are (2) Kitty and (3) Jen.
(c)
Difference in the number of circles between Kay and Jen
= 6 - 5
= 1
Number of buttons that Kay must give to Jen
= 1 ÷ 2 x 4
= 2
Answer(s): (a) 2; (b) 2, 3; (c) 2
