Charlie and Adam have 110 stickers.
Charlie has 10 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 = 10 u
Total number of stickers they have = 10 u + 1 u = 11
11 u = 110
1 u = 110 ÷ 11 = 10
Number of stickers that Adam has
= 1 u
= 10
(b)
Number of stickers that Charlie has
= 10 u
= 10 x 10
= 100
(c)
Number of stickers that Charlie has more than Adam
= 10 u - 1 u
= 9 u
= 9 x 10
= 90
(d)
Number of stickers that Adam has less than Charlie
= 10 u - 1 u
= 9 u
= 9 x 10
= 90
Answer(s): (a) 10; (b) 100; (c) 90; (d) 90
