Adam and Charlie have 40 stickers.
Adam has 4 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 = 4 u
Total number of stickers they have = 4 u + 1 u = 5
5 u = 40
1 u = 40 ÷ 5 = 8
Number of stickers that Charlie has
= 1 u
= 8
(b)
Number of stickers that Adam has
= 4 u
= 4 x 8
= 32
(c)
Number of stickers that Adam has more than Charlie
= 4 u - 1 u
= 3 u
= 3 x 8
= 24
(d)
Number of stickers that Charlie has less than Adam
= 4 u - 1 u
= 3 u
= 3 x 8
= 24
Answer(s): (a) 8; (b) 32; (c) 24; (d) 24
