Adam buys some stickers for his friends.
If he gives each of them 8 stickers, he needs another 2.
If he gives each of them 11 stickers, he needs another 20.
- How many friends are there?
- How many stickers does Adam buy?
(a)
Big difference
= 20 - 2
= 18
Small difference
= 11 - 8
= 3
Number of friends that Adam gives to
= 18 ÷ 3
= 6
(b)
Number of stickers that Adam buys
= 6 x 8 - 2
= 48 - 2
= 46
Answer(s): (a) 6; (b) 46
