Charlie and Bryan have 30 stickers.
Charlie has 9 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 = 9 u
Total number of stickers they have = 9 u + 1 u = 10
10 u = 30
1 u = 30 ÷ 10 = 3
Number of stickers that Bryan has
= 1 u
= 3
(b)
Number of stickers that Charlie has
= 9 u
= 9 x 3
= 27
(c)
Number of stickers that Charlie has more than Bryan
= 9 u - 1 u
= 8 u
= 8 x 3
= 24
(d)
Number of stickers that Bryan has less than Charlie
= 9 u - 1 u
= 8 u
= 8 x 3
= 24
Answer(s): (a) 3; (b) 27; (c) 24; (d) 24
