Charlie and Bryan have 90 stickers.
Charlie has 8 times as many stickers as Bryan.
- How many stickers does Bryan have?
- How many stickers does Charlie have?
- How many stickers does Charlie have more than Bryan?
- How many stickers does Bryan 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 Bryan has = 1 u
Number of stickers that Charlie has = 8 u
Total number of stickers they have = 8 u + 1 u = 9
9 u = 90
1 u = 90 ÷ 9 = 10
Number of stickers that Bryan has
= 1 u
= 10
(b)
Number of stickers that Charlie has
= 8 u
= 8 x 10
= 80
(c)
Number of stickers that Charlie has more than Bryan
= 8 u - 1 u
= 7 u
= 7 x 10
= 70
(d)
Number of stickers that Bryan has less than Charlie
= 8 u - 1 u
= 7 u
= 7 x 10
= 70
Answer(s): (a) 10; (b) 80; (c) 70; (d) 70
