Final answer:
The digit 4 represents 4 hundredths in the number 0.04, where 4 is placed in the hundredths position, right after the decimal point.
Step-by-step explanation:
The digit 4 represents a value of 4 hundredths in the number 0.04. When breaking down this number, we see that the 0 is in the tenths place, and the 4 is in the hundredths place. This placement of the digit 4 means that its value is 4 divided by 100, or 0.04.
This is because the place value of a digit becomes ten times smaller with each position we move to the right of the decimal point, hence the digit directly to the right of the decimal point is the tenths place, and the next one is the hundredths place. Understanding place value and decimal points is essential in handling such numbers.
