The graph shows the number of seashells 3 students collected. Study the graph and answer the following.
- Who collected 56 seashells? Give the answer in number. (Eg 1)
- Which 2 students collected a total of 96 seashells? Give the answer in numbers. (Eg 1, 2)
- How many seashells must Chloe give to Ruby so that both of them would have the same number of seashells?
(a)
8 seashells → 1 circle
56 seashells → 56 ÷ 8 = 7 circles
(2) Erny had 7 circles so she collected 56 seashells.
(b)
Total number of circles represented by 96 seashells
= 96 ÷ 8
= 12
Number of circles that Ruby and Erny had
= 7 + 5
= 12
2 students who collected a total of 96 seashells are (2) Erny and (3) Ruby.
(c)
Difference in the number of circles between Chloe and Ruby
= 6 - 5
= 1
Number of seashells that Chloe must give to Ruby
= 1 ÷ 2 x 8
= 4
Answer(s): (a) 2; (b) 2, 3; (c) 4
