Adam buys some stickers for his friends.
If he gives each of them 4 stickers, he needs another 2.
If he gives each of them 6 stickers, he needs another 16.
- How many friends are there?
- How many stickers does Adam buy?
(a)
Big difference
= 16 - 2
= 14
Small difference
= 6 - 4
= 2
Number of friends that Adam gives to
= 14 ÷ 2
= 7
(b)
Number of stickers that Adam buys
= 7 x 4 - 2
= 28 - 2
= 26
Answer(s): (a) 7; (b) 26
