when this 3 digit number is rounded to nearest 100, it rounds to 900. The digit in the ones place is the 5th odd number you count beginning with one. The sum of the digit is 22. What is this number.
The answer is 859. Because 9 is the fifth odd number counted and I know 8 is the number in the hundreds place. So I added the two and deducted it from 22 which was 5. 8+5+9=22
