Adam buys some stickers for his friends.
If he gives each of them 4 stickers, he has 2 stickers left.
If he gives each of them 6 stickers, he needs another 8.
- How many friends are there?
- How many stickers does Adam buy?
(a)
Big difference
= 2 + 8
= 10
Small difference
= 6 - 4
= 2
Number of friends that Adam gives to
= 10 ÷ 2
= 5
(b)
Number of stickers that Adam buys
= 5 x 4 + 2
= 20 + 2
= 22
Answer(s): (a) 5; (b) 22
