There is no biggest number that rounds to 110000. There is a smallest number that rounds higher. 110000.5, also represented by 110000.4999(infinitely repeating 9s) is the smallest number that rounds up to 110001.
110000.49 works, so does 110000.499, so does 110000.49999, so does 110000.4 followed by any FINITE string of 9s. But 110000.4 followed by an infinite string of 9s does not.
The reason there is no biggest number that works is that if you were to pick ANY number that works, I could simply go one decimal position further.
The numbers that round to 110000 form the half-open interval [109999.5,110000.5)
5% of 110000 = 110000*5/100 = 5500
30% of 110,000 = 30% * 110000 = 0.3 * 110000 = 33,000
110000 + 1 = 110001
It is 110000.
When rounding to the nearest whatever, half the number round up and half round down. → the numbers that round to 170000 to the nearest 10000 are 170000 ± (10000 ÷ 2) = 170000 ± 5000 However, if a number is exactly half way, the convention is to round them up, so the numbers in the range: 170000 - 5000 ≤ number < 170000 + 5000 → 165000 ≤ number < 175000 will round to 170000 to the nearest 10000 → smallest number is 165000 → biggest [whole] number is 175000 - 1 = 174999
4.2% of 110000 = 4.2% * 110000 = 0.042 * 110000 = 4,620

I suspect that a slash has been unilaterally stripped from your question and you were asking about one ten-thousandth of a metre. In this case 1/10000 = 1 ÷ 100000 = 0.00001 So 1/100000 m = 0.00001 m
20 percent of 1100 is 220
