Adam and Bryan have 80 stickers.
Adam has 9 times as many stickers as Bryan.
- How many stickers does Bryan have?
- How many stickers does Adam have?
- How many stickers does Adam have more than Bryan?
- How many stickers does Bryan have less than Adam?
(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 Adam has = 9 u
Total number of stickers they have = 9 u + 1 u = 10
10 u = 80
1 u = 80 ÷ 10 = 8
Number of stickers that Bryan has
= 1 u
= 8
(b)
Number of stickers that Adam has
= 9 u
= 9 x 8
= 72
(c)
Number of stickers that Adam has more than Bryan
= 9 u - 1 u
= 8 u
= 8 x 8
= 64
(d)
Number of stickers that Bryan has less than Adam
= 9 u - 1 u
= 8 u
= 8 x 8
= 64
Answer(s): (a) 8; (b) 72; (c) 64; (d) 64
