7 over 5
2 3/7 = 17/7 so its reciprocal is 7/17
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
1/3 x 6/7 = 6/21 = 2/7 The reciprocal is 7/2 1/3 x 7/6 = 7/18 The reciprocal is 18/7

yes
Oh, dude, the reciprocal of a number is just 1 divided by that number. So, the reciprocal of 2 is 1/2, and the reciprocal of 1/3 is 3. So, the reciprocal of 2 and 1/3 is 1/(2 + 1/3) which simplifies to 3/7. Easy peasy, like basic math stuff, you know?
9/7 is the reciprocal of 7/9.9/7
