Suppose the original number is x.
Then 1/x + 1/(x-4) = 6/x
Subtract 1/x form both sides: 1/(x-4) = 5/x
Take reciprocals of both sides: x - 4 = x/5
Multiply both sides by 5: 5x - 20 = x
Subtract x from both sides: 4x - 20 = 0
So 4x = 20 and so x = 5

2/x =16/20 16x = 40 x = 2.5
Number x Reciprocal = 1 Therefore Reciprocal = 1/Number
The reciprocal of a number is the inverse of that number. It is obtained by dividing 1 by the number. For example, the reciprocal of 5 is 1/5 and the reciprocal of 3/4 is 4/3.
The reciprocal of a number is what the original number is multiplied by to get 1. To find this you can simply divide 1 by the number you want the reciprocal for or, if the number is in fraction form, switch the denominator and numerator.
