Solution steps

\frac{3 π}{4} - π

Convert element to fraction:

π = \frac{π 4}{4}

= \frac{3 π}{4} - \frac{π 4}{4}

Since the denominators are equal, combine the fractions:

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

= \frac{3 π - π 4}{4}

Add similar elements:

3 π - 4 π = - π

= \frac{- π}{4}

Apply the fraction rule:

\frac{- a}{b} = - \frac{a}{b}

= - \frac{π}{4}

(\frac{5}{2})^{1}

3 n^{2} p + 12 n p - 27 n^{2} - 108 n

12 x - 66

- 10 + 3 x = 17

0.3 (n - 5) = 0.4 - 0.2 (n - 7)
