To express 73,200 as a decimal, we simply need to recognize that it is already in a whole number format. However, if we wanted to write it explicitly as a decimal, we can add ‘.0’ at the end, making it 73,200.0.
This shows that there are no additional digits after the decimal point, confirming that 73,200 is a whole number. In decimal form, it is essentially the same value, just represented differently.
