The graph shows the number of coins 3 students collected. Study the graph and answer the following.
- Who collected 16 coins? Give the answer in number. (Eg 1)
- Which 2 students collected a total of 40 coins? Give the answer in numbers. (Eg 1, 2)
- How many coins must Erny give to Emily so that both of them would have the same number of coins?
(a)
4 coins → 1 box
16 coins → 16 ÷ 4 = 4 boxes
(1) Fara has 4 boxes so she collected 16 coins.
(b)
Total number of boxes represented by 40 coins
= 40 ÷ 4
= 10
Number of boxes that Fara and Erny had
= 4 + 6
= 10
2 students who collected a total of 40 coins are (1) Fara and (3) Erny.
(c)
Difference in the number of boxes between Erny and Emily
= 6 - 5
= 1
Number of coins that Erny must give to Emily
= 1 ÷ 2 x 4
= 2
Answer(s): (a) 1; (b) 1, 3; (c) 2
