Adam buys some stickers for his friends.
If he gives each of them 5 stickers, he has 5 stickers left.
If he gives each of them 9 stickers, he needs another 27.
- How many friends are there?
- How many stickers does Adam buy?
(a)
Big difference
= 5 + 27
= 32
Small difference
= 9 - 5
= 4
Number of friends that Adam gives to
= 32 ÷ 4
= 8
(b)
Number of stickers that Adam buys
= 8 x 5 + 5
= 40 + 5
= 45
Answer(s): (a) 8; (b) 45
