rewrite each mixed number as a sum of two signed numbers.

we have a mixed fraction, and we are asked to rewrite it as the sum of two signed numbers, to do that let's remember that a mixed fraction is equivalent to the following:
[tex]A\frac{m}{n}=A+\frac{m}{n}[/tex]For the mixed fraction 3 1/5, we can rewrite it as:
[tex]3\frac{1}{5}=3+\frac{1}{5}[/tex]For the mixed fraction -7 3/8, we can rewrite it as:
[tex]-7\frac{3}{8}=-7+\frac{3}{8}[/tex]
