Adam buys some stickers for his friends.
If he gives each of them 6 stickers, he has 2 stickers left.
If he gives each of them 10 stickers, he needs another 10.
- How many friends are there?
- How many stickers does Adam buy?
(a)
Big difference
= 2 + 10
= 12
Small difference
= 10 - 6
= 4
Number of friends that Adam gives to
= 12 ÷ 4
= 3
(b)
Number of stickers that Adam buys
= 3 x 6 + 2
= 18 + 2
= 20
Answer(s): (a) 3; (b) 20
