7.2 = 36/5 (if you use the calculator to convert a decimal into a fraction)
Or you can work such as:
7.2
= 7 + 2/10
= 7 + 1/5 (or as a mixed number 7 1/5)
= 35/5 + 1/5
= 36/5 (as a rational number)
Or, you can do it the easy way. So easy you can do it in your head.
7.2 is the same as 72/10. Divide by 2 gives 36/5.
