To understand what the decimal number 0.75 means, we can break it down into its place value representation.
In the decimal system, each digit has a specific place value based on powers of 10. The digit to the left of the decimal point represents whole numbers, and the digits to the right represent fractions.
In this case, the number 0.75 has two digits to the right of the decimal point, which means it represents a fraction.
The first digit to the right of the decimal point is in the tenths place, and the second digit is in the hundredths place.
So, when we read the number 0.75, we say "seventy-five hundredths."
Therefore, the correct answer is D. seventy-five tenths of a whole unit.
