Bryan and Adam have 70 stickers.
Bryan has 9 times as many stickers as Adam.
- How many stickers does Adam have?
- How many stickers does Bryan have?
- How many stickers does Bryan have more than Adam?
- How many stickers does Adam 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 Adam has = 1 u
Number of stickers that Bryan has = 9 u
Total number of stickers they have = 9 u + 1 u = 10
10 u = 70
1 u = 70 ÷ 10 = 7
Number of stickers that Adam has
= 1 u
= 7
(b)
Number of stickers that Bryan has
= 9 u
= 9 x 7
= 63
(c)
Number of stickers that Bryan has more than Adam
= 9 u - 1 u
= 8 u
= 8 x 7
= 56
(d)
Number of stickers that Adam has less than Bryan
= 9 u - 1 u
= 8 u
= 8 x 7
= 56
Answer(s): (a) 7; (b) 63; (c) 56; (d) 56
