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