She should go over her division and check it carefully.
The actual quotient is about 31% less than her estimate.
That's too much. Estimating isn't worth anything if it can't
get a lot closer than that. There's almost certainly a mistake
in either the estimate or the actual quotient ... maybe even in
both ... and Lilly needs to find it.
She probably needs the actual quotient, whether for her
business, or her homework, or her job, and she probably did
the estimate just for her own convenience. That's why I suggest
that she should check the actual quotient first. If she finds the
mistake there, then she can fix it, and she doesn't need to check
the estimate. If she doesn't find a mistake in the actual quotient,
then she'll have to check the estimate.
Either way ... a disagreement of 31% is too much. Something doesn't
compute somewhere, and she needs to find it.
