In an activity, Mary collected 492 beads. She collected 4 times as many beads as Xuan.
- How many beads did Xuan collect?
- How many more beads did Mary collect than Xuan?
(a)
Number of beads that Xuan collected = 1 u
Number of beads that Mary collected = 4 u = 492
4 u = 492
1 u = 492 ÷ 4 = 123
Number of beads that Xuan collected
= 1 u
= 123
(b)
Number of beads that Mary collected more than Xuan
= 492 - 123
= 369
Answer(s): (a) 123; (b) 369
