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