Final answer:
Subtracting one hundredth (0.01) from 7.3 gives us 7.29, after borrowing from the tenths place.
Step-by-step explanation:
The number that is one hundredth (0.01) less than 7.3 is simply 7.3 minus 0.01, which equals 7.29. Subtracting one hundredth from a decimal number involves decreasing the amount in the hundredths place by one, provided that place exists. In this case, the hundredths place is occupied by a 0, and subtracting 1 from 0 requires borrowing from the tenths place. Therefore, the 3 in the tenths place becomes a 2, and we borrow 10 hundredths which then gives us a 9 in the hundredths place after subtraction.
