Adam buys some stickers for his friends.
If he gives each of them 6 stickers, he has 19 stickers left.
If he gives each of them 8 stickers, he has 3 stickers left.
- How many friends are there?
- How many stickers does Adam buy?
(a)
Big difference
= 19 - 3
= 16
Small difference
= 8 - 6
= 2
Number of friends that Adam gives to
= 16 ÷ 2
= 8
(b)
Number of stickers that Adam buys
= 8 x 6 + 19
= 48 + 19
= 67
Answer(s): (a) 8; (b) 67
