So you divide 200 by 100 so 210/100, thats when you get 2.1. So to convert that from percent to decimal all you do is is just divide by 100 and remove the % sign! Just move the decimal point 2 places to the left. If the percent value is a integer, the '.' is at the right of the right most digit.

Hope this helped you out and hope you got your answer right! Enjoy the rest of your day. :)

Three angels are labeled below with arcs. The smallest angel is 3/8 as large as the 160 degree angel. Find the value of angel a

gladu [14]

$the\ smaller\ angle= \frac{3}{8} \cdot 160^0=\frac{3}{8} \cdot \frac{160^0}{1} = \frac{3\cdot20^0}{1} =60^0\\ \\a=360^0-(160^0+60^0)=360^0-220^0=140^0$

Rewrite the radicand as two factors, one of which is a perfect cube. <br><br> 3/250

a^{-n} \implies \cfrac{1}{a^n}
\qquad \qquad
\cfrac{1}{a^n}\implies a^{-n}
\qquad \qquad 
a^n\implies \cfrac{1}{a^{-n}}
\\\\
-------------------------------\\\\
\cfrac{3}{250}\qquad 
\begin{cases}
250=2\cdot 5\cdot 5\cdot 5\\
\qquad 2\cdot 5^3
\end{cases}\implies \cfrac{3}{5^3\cdot 2}\implies \cfrac{1}{5^3}\cdot \cfrac{3}{2}
\\\\\\
5^{-3}\cdot \cfrac{3}{2}\implies (5^{-1})^3\cdot \cfrac{3}{2}$
