find two consecutive natural number the sum of whose reciprocal is 11/30
n = ist number
n+1 = second number
the sum: n + n + 1 or 2n + 1
reciprocal we would want 1/(2n+1)
and that should equal 11/30
Set the two fractions equal to each other
Cross multiply and then solve for n.
then find n+1
want the answer of Quadratic Eqution- Divide 20 into two parts so that their sum of their reciprocals is4/15
