Adam buys some stickers for his friends.
If he gives each of them 8 stickers, he has 3 stickers left.
If he gives each of them 11 stickers, he needs another 9.
- How many friends are there?
- How many stickers does Adam buy?
(a)
Big difference
= 3 + 9
= 12
Small difference
= 11 - 8
= 3
Number of friends that Adam gives to
= 12 ÷ 3
= 4
(b)
Number of stickers that Adam buys
= 4 x 8 + 3
= 32 + 3
= 35
Answer(s): (a) 4; (b) 35
