Adam buys some stickers for his friends.
If he gives each of them 5 stickers, he has 2 stickers left.
If he gives each of them 7 stickers, he needs another 10.
- How many friends are there?
- How many stickers does Adam buy?
(a)
Big difference
= 2 + 10
= 12
Small difference
= 7 - 5
= 2
Number of friends that Adam gives to
= 12 ÷ 2
= 6
(b)
Number of stickers that Adam buys
= 6 x 5 + 2
= 30 + 2
= 32
Answer(s): (a) 6; (b) 32
