When's the 3 digit number is rounded to the nearest hundred it round to 400.The digit in the ones place is the fourth odd number you count beginning with 1.The sum of the digits is 12.What is the number

Cannot be determined since the question is wrong.

Step-by-step explanation:

The fourth odd number is: 1, 3, 5, 7

h+t+o=12

h+t+7=12

Subtract 7 from both sides

h+t=5

If it rounds up to 400, h must be 3.

3+t=5

Subtract 3 from both sides

t=2

So our number is 327? It doesn't round up to 400 so the question is probably wrong. You probably got a typo in their like the numbers adding up to 12 or rounding to 300.
