How can I simplify this and show work?

svp [43]

$\frac{ \sqrt{3}}{ \sqrt{5} - \sqrt{6} } \\ = \frac{ \sqrt{3}( \sqrt{5} + \sqrt{6}) }{( \sqrt{5} - \sqrt{6})( \sqrt{5} + \sqrt{6})} \\ = \frac{ \sqrt{15}+3 \sqrt{2} }{5-6} \\ =- \sqrt{15}-3 \sqrt{2}$

Can someone explain how the answer to #14 is 7/8 in;0.875 in.

Tamiku [17]

Of the 16 small intervals indicated from 0 to 1 inch, the ant spans 14 of them, so

$\dfrac{14}{16} = \dfrac{7}{8} \textrm{ inches} = 0.875 \textrm{ in}$

How is 7/8 equal to 0.875?

Since 125(8)=1000 and 125(7)=875 we know

$\dfrac{7}{8} = \dfrac{7 \cdot 125}{8 \cdot 125} = \dfrac{875}{1000} = 0.875$
