It is equal because after the decimal point it goes tenths, hundereths, thousandths, etc. Since it is two decmal paces to the right, it would be hundereths. So, 73/100 is equal to 0.73
yes because if you just simply change the decimal point to a fraction you will get 73/100 it is a double-digit number so you have to use the 100 and not a one as the denominator.
