# How do you simplify ( x +1) / 2 - (w/2)?

Apr 12, 2018

$\frac{x - w + 1}{2}$

#### Explanation:

To subtract fractions, make sure that both fractions have the same denominator.

Same denominators:

$\frac{2}{3} , \frac{14}{3}$

$- \frac{8}{11} , \frac{19}{11}$

Not the same denominators:

$\frac{1}{4} , \frac{2}{7}$

$- \frac{13}{17} , \frac{89}{64}$

These two fractions both have the denominator of 2.

To subtract, simply subtract the numerator of the second fraction from the first:

$\frac{x + 1 - w}{2}$

$\frac{x - w + 1}{2}$
