Question

Lilly estimated a quotient of 120 and found an actual quotient of 83, what should she do next, explain

Answer 1

She needs to find out why her estimate is so far away from the actual answer (over 50%). It could be that she picked unsuitable compatible numbers, or she found suitable numbers but didn't apply them properly. So Lilly should check her substitute numbers and the arithmetic she carried out. Estimates are sums that can easily be done in your head, so perhaps the mental calculation wasn't as easy as she thought!
