Question

If 1/2 is subtracted from four times the reciprocal of a number, the result is 0. Find the number.

Answer 1

The Number is 8.

Explanation:

Let the number be x.

Given:

1/2 is subtracted from four times the reciprocal of a number, the result is 0.

Hence the equation will become like;

`4* (1)/(x) - (1)/(2)=0`

Now Solving the equation we get.

`(4)/(x) -(1)/(2)=0\\\\(4)/(x) = (1)/(2)\\\\x= 4* 2\\x=8`

Now the we can see the number is 8, when 1/2 is subtracted from 4 times the reciprocal of number means 4/8 which becomes 1/2 and hence when 1/2 is subtracted from 1/2 it equals to 0.

Hence the number is 8.
