Hello,
you are supposed to know that every (integer) number can be written as a fraction: $\displaystyle 13 = \frac{13}{1}$
With this property your division becomes:
$\displaystyle -\frac{65}{7} \div 13 = -\frac{\frac{65}{7}}{\frac{13}{1}} = -\frac{\not{6}\not{5}^5}{7} \cdot \frac{1}{\not{1}\not{3}_1} = -\frac57$
My problem is the canceling I guess.
I knew to take the recipricole of 13 and change the operation to Multiplication. Then I just thought you multiply the Numerators and Denominators across.
when you have the problem set up as:
65/7 x 1/13 =
are you supposed to cross divide?
thanx for your help.
