Estimate the quotient of 5421 and 21

this approximates to 5000 / 20

=  250

The easiest way to estimate is to round both numbers to an easier number to work with. So we'd round 5,421 to 5,400, and 21 to 20. Then, we would divide 5,400 by 20 in our heads. Well that's easy because we know 20 x 270 is 5,400. So we can estimate that 5,421/21 is CLOSE to 270. Are we right?

5,421/21= 258

We were close, and that's as close as we will get when estimating. Hope that helps! Mark Brainliest if it does (if the brainliest button doesn't show up, just refresh the page). Thank you!
