Answer:

Numbers can be 10 and 5

Numbers can be -5 and -10

Step-by-step explanation:

Let the number be x

Reciprocal of number= \frac{1}{x}

Since we are given that the difference of two numbers is 5.

So, second number = x-5

reciprocal = \frac{1}{x-5}

Since we are given that the difference of their reciprocal is 1/10

So, \frac{1}{x} -\frac{1}{x-5} =\frac{1}{10}

x-5 -x=\frac{1}{10} \times(x)(x-5)

50=(x)(x-5)

x^2-5x-50=0

x^2-10x+5x-50=0

x(x-10)+5(x-10)=0

(x-10)(x+5)=0

x=10,-5

If x = 10

So, numbers can be 10 and x-5=10-5=5

if x = -5

So, numbers can be -5 and x-5=-5-5=-10
