Rounding to the nearest 1000 (thousand)

When rounding to the nearest 1000, count in 1000's either side of your number and choose the nearest.

If the number in the hundreds place is less than 5 then round down, if the number in the hundreds place is 5 or greater then round up.

93 235 is between 93 000 and 94 000.

93 000 <——93 235——————> 94 000

There is a 200 in the hundreds place, so round down to 93 000.

93 235 is 93000 rounded to the nearest 1000.

Rounding to the nearest 10 000 (ten thousand)

When rounding to the nearest 10 000, count in 10 000's either side of your number and choose the nearest.

If the number in the thousands place is less than 5 then round down, if the number in the thousands place is 5 or more, round up!

369 594 is between 360 000 and 370 000.

360 000 <—————369 594 ———> 370 000

There is a 9 in thousands place, so round up to 370 000.

369 594 is 370000 rounded to the nearest 10 000.

Rounding to the nearest 100 000 (hundred thousand)

When rounding to the nearest 100 000, count in 100 000's either side of your number and choose the nearest.

If the number in the ten thousands place is less than 5 then round down, if the number in the ten thousands place is 5 or more, round up!

8 439 798 is between 8 400 000 and 8 500 000.

8 400 000 <———8 439 798—————> 8 500 000

There is a 3 in the ten thousands place, so round down to 8 400 000.

8 439 798 is 8400000 rounded to the nearest 100 000.

Rounding to the nearest 1 000 000 (million)

When rounding to the nearest 1 000 000, count in 1 000 000's either side of your number and choose the nearest.

If the number in the hundred thousands place is less than 5 then round down, if the number in the hundred thousands place is 5 or more, round up!

8 500 000 is between 8 000 000 and 9 000 000.

8 000 000 <———8 500 000———> 9 000 000

The number in the hundred thousands place is 5, so we round up to 9 000 000.

8 500 000 is 9000000 rounded to the nearest 1 000 000.
