Suppose the number is x. Then x + 5/x = 6
Multiplying throughout by x, x2+5 = 6x or x2 - 6x + 5 = 0
which can be factorised into (x-1)*(x-5)=0
So x = 1 (and 5 times its reciprocal is 5)
or x = 5 (and 5 times its reciprocal is 1).

What is the reciprocal of 2 and three fourths?
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.
