In an activity, Opal collected 300 erasers. She collected 5 times as many erasers as Cindy.
- How many erasers did Cindy collect?
- How many more erasers did Opal collect than Cindy?
(a)
Number of erasers that Cindy collected = 1 u
Number of erasers that Opal collected = 5 u = 300
5 u = 300
1 u = 300 ÷ 5 = 60
Number of erasers that Cindy collected
= 1 u
= 60
(b)
Number of erasers that Opal collected more than Cindy
= 300 - 60
= 240
Answer(s): (a) 60; (b) 240
