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