Step-by-step explanation:
A school needs 2,2337 notepads. They come in packs of 20. This is a common question.
Start by finding out how many packs of 20 go into 2,337. This is done by doing the division 2337 ÷ 20. This finds the answer 116. The remainder is 17. Hmm. The school cannot buy 116 packs of notepads otherwise they would be 17 short ( the remainder), so they buy one extra pack-117 packs. This extra pack covers the extra 17, even though there are no packs of 17, only 20. This means they will have three spare.
The answer is 117 packs.
