Question

Which equation uses estimation to find the quotient of 421-:73 ?

Answer 1

To use estimation to find the quotient of 421 ÷ 73, we can round the numbers to the nearest tens or hundreds place and perform the division.

Explanation:

Here's an example using rounding to the nearest tens place:

Round 421 to 420 (nearest tens)

Round 73 to 70 (nearest tens)

Then, perform the division:

420 ÷ 70 = 6

So, the estimation using rounding to the nearest tens place gives an approximate quotient of 6 for 421 ÷ 73.

Alternatively, you can also use rounding to the nearest hundreds place:

Round 421 to 400 (nearest hundreds)

Round 73 to 70 (nearest tens)

Then, perform the division:

400 ÷ 70 = 5.71
