In an activity, Tammy collected 402 erasers. She collected 3 times as many erasers as Marion.
- How many erasers did Marion collect?
- How many more erasers did Tammy collect than Marion?
(a)
Number of erasers that Marion collected = 1 u
Number of erasers that Tammy collected = 3 u = 402
3 u = 402
1 u = 402 ÷ 3 = 134
Number of erasers that Marion collected
= 1 u
= 134
(b)
Number of erasers that Tammy collected more than Marion
= 402 - 134
= 268
Answer(s): (a) 134; (b) 268
