Ok, so let x be the number and write the word phrase as an equation....
1/(x-4)=2(1/x)
1/(x-4)=2/x
Flip them...
x-4=x/2
times 2...
2x-8=x
move the x, so...
x=8
And your welcome ^-^ (asian brain power)

What is the reciprocal of 5 less than a number is 4 times the reciprocal of twice the number what's the number?
Suppose the number is x. Then 1/(x-5) = 4*(1/2x) Multiply both sides by x*(x-5) to give: x = 4*(x-5)/2 = 2*(x-5) = 2x - 10 and so x = 10
