Answer 1

So we need a common denominator, and we'll choose 16 since that is common to both terms. What we do to the bottom of a fraction, we must also do to the top of the fraction, so in order to transform the fraction, we must do the following:

$\frac{1}{8}*\frac{2}{2}=\frac{2}{16}$

Now that we have this fraction with the correct denominator, we can subtract and solve the equation:

$\frac{5}{16} -\frac{2}{16} =\frac{3}{16}$

Since $\frac{3}{16}$ cannot be reduced any further, we are going to leave this as the answer.

So now we now that the answer is $\frac{3}{16}$.
