4 over 5
The answer is: 2/7 More information from "http://en.allexperts.com/q/Basic-Math-657/reciprocal.htm": A reciprocal is a number that you multiply by so that the result equals 1. The easiest way to find it is to just flip the fraction over. Here's an example: What is the reciprocal of 3? 3 is the same as 3/1, so we flip and the reciprocal is 1/3 Reciprocal of 4/5 is 5/4 Reciprocal of 2 1/2? Trciky! Change to a fraction --> 5/2, then flip --> 2/5

5/34
to find the reciprocal you would want to make 2 3/4 an impropper fraction. To do that you need to multiply the whole number by the denominator. In this case the 2 by the 4. From that you get 8. Then you add that number to the numerator. So it would be 8+3=11. Put this number over 4 and you have 11/4. Then you can find the reciprocal which would be that number upside down. Your reciprocal is 4/11.
15/4 divided by 5/4= 15/4 x 4/5 because 5/4's reciprocal is 4/5. you get 60/20 or 3/2. so, 3 over 2.
