Adam buys some stickers for his friends.
If he gives each of them 6 stickers, he has 4 stickers left.
If he gives each of them 9 stickers, he needs another 11.
- How many friends are there?
- How many stickers does Adam buy?
(a)
Big difference
= 4 + 11
= 15
Small difference
= 9 - 6
= 3
Number of friends that Adam gives to
= 15 ÷ 3
= 5
(b)
Number of stickers that Adam buys
= 5 x 6 + 4
= 30 + 4
= 34
Answer(s): (a) 5; (b) 34
