Charlie and Bryan have 30 stickers.
Charlie has 4 times as many stickers as Bryan.
- How many stickers does Bryan have?
- How many stickers does Charlie have?
- How many stickers does Charlie have more than Bryan?
- How many stickers does Bryan 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 Bryan has = 1 u
Number of stickers that Charlie has = 4 u
Total number of stickers they have = 4 u + 1 u = 5
5 u = 30
1 u = 30 ÷ 5 = 6
Number of stickers that Bryan has
= 1 u
= 6
(b)
Number of stickers that Charlie has
= 4 u
= 4 x 6
= 24
(c)
Number of stickers that Charlie has more than Bryan
= 4 u - 1 u
= 3 u
= 3 x 6
= 18
(d)
Number of stickers that Bryan has less than Charlie
= 4 u - 1 u
= 3 u
= 3 x 6
= 18
Answer(s): (a) 6; (b) 24; (c) 18; (d) 18
