    6               7              2           7              2           6

now round the number to nearest hundred thousand.

hundred thousand digit in 672726 is 7

If rounding number is greater than equal to 5 then next number increase by 1.

If rounding number is less than 5 then next number does not change.

here rounding number is 7 > 5

So, next digit 6 change to 7

Rounded number  = 700 000

672 726   → 700 000

Andrew did
