Charlie and Adam have 60 stickers.
Charlie has 9 times as many stickers as Adam.
- How many stickers does Adam have?
- How many stickers does Charlie have?
- How many stickers does Charlie have more than Adam?
- How many stickers does Adam have less than Charlie?
(a)
Focus on the sentence with the word 'times'.
Assign 1 u to the variable that is found after the word 'times'.
Number of stickers that Adam has = 1 u
Number of stickers that Charlie has = 9 u
Total number of stickers they have = 9 u + 1 u = 10
10 u = 60
1 u = 60 ÷ 10 = 6
Number of stickers that Adam has
= 1 u
= 6
(b)
Number of stickers that Charlie has
= 9 u
= 9 x 6
= 54
(c)
Number of stickers that Charlie has more than Adam
= 9 u - 1 u
= 8 u
= 8 x 6
= 48
(d)
Number of stickers that Adam has less than Charlie
= 9 u - 1 u
= 8 u
= 8 x 6
= 48
Answer(s): (a) 6; (b) 54; (c) 48; (d) 48
