In an activity, Tammy collected 255 erasers. She collected 5 times as many erasers as Opal.
- How many erasers did Opal collect?
- How many more erasers did Tammy collect than Opal?
(a)
Number of erasers that Opal collected = 1 u
Number of erasers that Tammy collected = 5 u = 255
5 u = 255
1 u = 255 ÷ 5 = 51
Number of erasers that Opal collected
= 1 u
= 51
(b)
Number of erasers that Tammy collected more than Opal
= 255 - 51
= 204
Answer(s): (a) 51; (b) 204
