Re: Dividing Decimals Help please TEST SOON!

$\displaystyle {7 \over 9.22} = {{7 \times 100} \over {9.22 \times 100}}= {700 \over 922}$

Can you divide now?

Quote:

Find $\displaystyle \sin^{-1}{\left({7 \over 9.22} \right)}$

$\displaystyle \sin^{-1}{\left({7 \over 9.22} \right)}=\sin^{-1}{\left({700 \over 922} \right)}$

Draw a right-angled triangle with Perpendicular = 700 and Hypotenuse = 922.

Now measure $\displaystyle \angle A$.

Edit: It would be easier if you draw perpendicular=7 and hypotenuse=9.22 .
