Question

Which expression is equivalent to the following complex fraction?

1 minus StartFraction 1 Over x EndFraction divided by 2

Answer 1

Answer: A

x - 1 / 2x

Answer 2

(2x-1)/2x

Explanation:

Given the function 1-(1/x÷2)

Using the rule of BODMAS

Solving the equation in bracket first, will give;

1/x÷2

= 1/x×1/2

= 1/2x

The equation then becomes

1-1/2x

Next is to look for the LCM of the resulting equation

1-1/2x

= (2x-1)/2x

The expression equivalent to the fraction is (2x-1)/2x
