Question

Please help? how do i solve (23pi/4)-pi ?

Answer 1

\[\frac{ 23\pi }{ 4 } - \pi\]

Answer 2

fyi, you can simplify or rewrite it. but "solve" means something else.

think of this as adding two fractions or a fraction and a whole number.
you need a "common denominator"
once you have the same "bottom" for both, you add or subtract the tops, and keep the same bottom

I would multiply the second number by 4/4 as the first step

Answer 3

\[ \frac{ 23\pi }{ 4 } - \pi \\\frac{ 23\pi }{ 4 } - \frac{4\pi}{4}\]
now subtract the tops
\[ \frac{23\pi-4\pi}{4}\]

up top you have 23 pi's take away 4 pi's , leaving 19 pi
so the simplified form is
\[ \frac{19\pi}{4}\]
