Adam and Charlie have 60 stickers.
Adam has 5 times as many stickers as Charlie.
- How many stickers does Charlie have?
- How many stickers does Adam have?
- How many stickers does Adam have more than Charlie?
- How many stickers does Charlie 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 Charlie has = 1 u
Number of stickers that Adam has = 5 u
Total number of stickers they have = 5 u + 1 u = 6
6 u = 60
1 u = 60 ÷ 6 = 10
Number of stickers that Charlie has
= 1 u
= 10
(b)
Number of stickers that Adam has
= 5 u
= 5 x 10
= 50
(c)
Number of stickers that Adam has more than Charlie
= 5 u - 1 u
= 4 u
= 4 x 10
= 40
(d)
Number of stickers that Charlie has less than Adam
= 5 u - 1 u
= 4 u
= 4 x 10
= 40
Answer(s): (a) 10; (b) 50; (c) 40; (d) 40
