$\frac {2}{5}\div \frac {5}{6}$

Remember when dividing fraction just flip and multiply:

$\frac {2}{5}\div \frac {5}{6}=\frac {2}{5}\cdot \frac {6}{5}$

Then just multiply the numerator by the numerator and the denominator by the denominator.

$(4)-(-5)$

Remember that subtracting a negative number is the same as adding that number:

$(4)-(-5)=4+5$

Then just add.

$18\div (-3)$

This is just the same as normal division, except you have to remember to keep the minus sign:

$18\div (-3)=-6$
