Adam buys some stickers for his friends.
If he gives each of them 8 stickers, he has 16 stickers left.
If he gives each of them 10 stickers, he has 6 stickers left.
- How many friends are there?
- How many stickers does Adam buy?
(a)
Big difference
= 16 - 6
= 10
Small difference
= 10 - 8
= 2
Number of friends that Adam gives to
= 10 ÷ 2
= 5
(b)
Number of stickers that Adam buys
= 5 x 8 + 16
= 40 + 16
= 56
Answer(s): (a) 5; (b) 56
