Which expression is equivalent to the following complex fraction? 1-1/x/2x

(x − 1) / (2x)

Step-by-step explanation:

I assume you mean (1 − (1/x)) / 2.

Find the common denominator of 1 and 1/x.

((x/x) − (1/x)) / 2

((x − 1) / x) / 2

Multiply by the reciprocal of 2.

((x − 1) / x) × (1/2)

(x − 1) / (2x)

(x-1) /2x

Step-by-step explanation:

(1-1/x)/2

(1 - 1/x) ÷ 2

copy dot flip for the division

(1 - 1/x) * 1/2

Getting a common denominator in the parentheses

(x-1)/x *1/2

(x-1) /2x
