One number is 4 times another. If the sum of their reciprocals is 5/36 , find the two numbers.

I am total lost on this problem

x is a number
4x is another number
these should = 5/36

so my equation would be
x+4x=5/36

first x i am getting 1/36
so the second would be 4/36=9
the two numbers be 1/36, 9

please explain to me what i have done wrong

the sum of their RECIPROCALS. which isn't x+4x

reciprocal of 5/36 is 36/5=7.2
x =4x=7.2

One number is 4 times another. If the sum of their reciprocals is 5/36 , find the two numbers.

x = 2y

1/x + 1/y = 5/36

You should be able to take it from here.
