In an activity, Gabby collected 390 marbles. She collected 6 times as many marbles as Shiyun.
- How many marbles did Shiyun collect?
- How many more marbles did Gabby collect than Shiyun?
(a)
Number of marbles that Shiyun collected = 1 u
Number of marbles that Gabby collected = 6 u = 390
6 u = 390
1 u = 390 ÷ 6 = 65
Number of marbles that Shiyun collected
= 1 u
= 65
(b)
Number of marbles that Gabby collected more than Shiyun
= 390 - 65
= 325
Answer(s): (a) 65; (b) 325
