In an activity, Gwen collected 315 marbles. She collected 3 times as many marbles as Pamela.
- How many marbles did Pamela collect?
- How many more marbles did Gwen collect than Pamela?
(a)
Number of marbles that Pamela collected = 1 u
Number of marbles that Gwen collected = 3 u = 315
3 u = 315
1 u = 315 ÷ 3 = 105
Number of marbles that Pamela collected
= 1 u
= 105
(b)
Number of marbles that Gwen collected more than Pamela
= 315 - 105
= 210
Answer(s): (a) 105; (b) 210
