In an activity, Irene collected 500 beads. She collected 4 times as many beads as Risa.
- How many beads did Risa collect?
- How many more beads did Irene collect than Risa?
(a)
Number of beads that Risa collected = 1 u
Number of beads that Irene collected = 4 u = 500
4 u = 500
1 u = 500 ÷ 4 = 125
Number of beads that Risa collected
= 1 u
= 125
(b)
Number of beads that Irene collected more than Risa
= 500 - 125
= 375
Answer(s): (a) 125; (b) 375
