Answer:
30
Step-by-step explanation:
Each digit in a whole number has a place value, based on its position from the decimal point.
The place value of a digit increases by a factor of 10 as we move left on the place value chart and decreases by a factor of 10 as we move right.
Numbers to the left of the decimal point increase in place value in the order: ones, tens, hundreds, etc.
The value of a digit is the digit multiplied by its place value.
So, the digit 3 in 731.8 has a value of 30.
