Adam buys some stickers for his friends.
If he gives each of them 4 stickers, he has 4 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
= 4 + 8
= 12
Small difference
= 6 - 4
= 2
Number of friends that Adam gives to
= 12 ÷ 2
= 6
(b)
Number of stickers that Adam buys
= 6 x 4 + 4
= 24 + 4
= 28
Answer(s): (a) 6; (b) 28
