72/5. You have to calculate how many times 5 will go into 72 evenly (you may have left over numbers). So 5 goes into 72, 14 times with 2 left over. so the Mixed number will be 14 2/5. you take the left over numbers and make the numerator, over the original denominator. hehe.
You need to call your number "x", then write the following two equations:(Equation 1) x = 0.727272... Multiplying by 100, you get: (Equation 2) 100x = 72.727272... If you subtract equation 1 from equation 2, and solve for "x", you will get the number as a fraction.
The answer is 72! :)
