Adam and Bryan have 50 stickers.
Adam has 4 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 = 4 u
Total number of stickers they have = 4 u + 1 u = 5
5 u = 50
1 u = 50 ÷ 5 = 10
Number of stickers that Bryan has
= 1 u
= 10
(b)
Number of stickers that Adam has
= 4 u
= 4 x 10
= 40
(c)
Number of stickers that Adam has more than Bryan
= 4 u - 1 u
= 3 u
= 3 x 10
= 30
(d)
Number of stickers that Bryan has less than Adam
= 4 u - 1 u
= 3 u
= 3 x 10
= 30
Answer(s): (a) 10; (b) 40; (c) 30; (d) 30
