Charlie and Adam have 80 stickers.
Charlie has 7 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 = 7 u
Total number of stickers they have = 7 u + 1 u = 8
8 u = 80
1 u = 80 ÷ 8 = 10
Number of stickers that Adam has
= 1 u
= 10
(b)
Number of stickers that Charlie has
= 7 u
= 7 x 10
= 70
(c)
Number of stickers that Charlie has more than Adam
= 7 u - 1 u
= 6 u
= 6 x 10
= 60
(d)
Number of stickers that Adam has less than Charlie
= 7 u - 1 u
= 6 u
= 6 x 10
= 60
Answer(s): (a) 10; (b) 70; (c) 60; (d) 60
