No, because 7.2 is basically the number 7 with a decimal point that says .2.
72 is a greater number because 7 is less than 72. Like 3.3 wouldn't be the same as 33 for example because 33 is greater than 3. Take out the decimal from 7.2 for a second and ask yourself "Is 72 greater than 7?" Once you ask yourself that you should be able to answer other question similar to that one. I hope this helped!
