Archie had
18 as many stickers as Ryan. Ryan had twice as many stickers as Ken. If Archie had 84 stickers fewer than Ken,
- how many stickers did Archie have?
- how many stickers did they have altogether?
(a)
Number of stickers that Archie had = 1 u
Number of stickers that Ryan had = 8 u
Number of stickers that Ken had = 8 u ÷ 2 = 4 u
Number of stickers that Archie had fewer than Ken
= 4 u - 1 u
= 3 u
3 u = 84
1 u = 84 ÷ 3 = 28
Number of stickers that Archie had
= 1 u
= 28
(b)
Total number of stickers that they had
= 1 u + 8 u + 4 u
= 13 u
= 13 x 28
= 364
Answer(s): (a) 28; (b) 364
