Question

rounding off numbers 90 000 and 100000​

Answer 1

Answer:

If the digit in the thousand’s place in a number is 0, 1, 2, 3 or 4 then round to the nearest multiple of ten thousand which is smaller than the given number.

If the digit in the thousand’s place in a number is 5, 6, 7, 8 or 9 then round to the nearest multiple of ten thousand which is greater than the given number.

Thus, to round off numbers to the nearest ten thousand look at the digit in the one thousands place.

For example, round the following numbers to the nearest ten thousand

T. Th    Th           H             T            O

4          6           2             7            9        →            50000

8          0           1             5            3        →            80000

6          5           0             0            0        →            70000

9          6           2             5            1        →           100000

8          3           1             0            1        →             80000

Rounding off to the nearest hundred thousand (100,000):
