Liam bought some pineapples and repacked them into packets of 21. He had 143 such packets of pineapples and 9 pineapples left.
- How many pineapples did Liam buy?
- Liam wanted to have 150 packets of pineapples. How many more pineapples must he buy?
(a)
Number of pineapples that Liam bought
= 143 x 21 + 9
= 3003 + 9
= 3012
(b)
Number of pineapples required for 21 packets
= 21 x 150
= 3150
Number of more pineapples that Liam must buy
= 3150 - 3012
= 138
Answer(s): (a) 3012; (b) 138
