Charlie and Adam have 30 stickers.
Charlie has 5 times as many stickers as Adam.
- How many stickers does Adam have?
- How many stickers does Charlie have?
- How many stickers does Charlie have more than Adam?
- How many stickers does Adam 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 Adam has = 1 u
Number of stickers that Charlie has = 5 u
Total number of stickers they have = 5 u + 1 u = 6
6 u = 30
1 u = 30 ÷ 6 = 5
Number of stickers that Adam has
= 1 u
= 5
(b)
Number of stickers that Charlie has
= 5 u
= 5 x 5
= 25
(c)
Number of stickers that Charlie has more than Adam
= 5 u - 1 u
= 4 u
= 4 x 5
= 20
(d)
Number of stickers that Adam has less than Charlie
= 5 u - 1 u
= 4 u
= 4 x 5
= 20
Answer(s): (a) 5; (b) 25; (c) 20; (d) 20
