solution

You want to find which expression will give a better estimate for

184

Look at

180

180 is close to 184, and 30 is close to 33. 180 can be easily divided by 30. So,

180

is a good way to estimate

184

Look at

190

190 is also close to 184. However,

190

cannot be easily divided. These numbers do not make estimating

184

easy.

So,

180

is a better way to estimate.

Now, use

180

to estimate the quotient.

Use basic division facts and division patterns to help you.
