Answer:
615,000
Explanation:
Given that:
Whole number rounded to the nearest ten thousand is 620,000
Let x = the whole number
HTh__ TTh ____ Th ____ H ____ T ____ U
6_____ 2 ______ 0 ____ 0 ____ 0 ____ 0
The ten thousand digit is 0 ;
To round to the nearest 10 thousand, the thousand digit is rounded up to 1 and added to the ten thousand digit if it up to 5 or above and rounded down to 0 if below 5 with all subsequent digits(hundred, tens and unit) rounded to Zero..
Hence,
The whole number will could be range between :
615,000 - 619,999
Hence, the least possible value for the number is 615,000.
