    \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
