Answer:
[tex]-\frac{8}{5}[/tex]
Step-by-step explanation:
First, let's write both of these numbers as improper fractions. We find that [tex]1\frac{4}{5}[/tex] becomes [tex]\frac{9}{5}[/tex] , and [tex]-3\frac{4}{10}[/tex] becomes [tex]-\frac{34}{10}[/tex] . Be mindful that when adding two fractions, the denominator must be the same. So we now must make [tex]\frac{9}{5}[/tex] into [tex]\frac{18}{10}[/tex] . (I did this by doing : [tex]\frac{9}{5}[/tex] × [tex]\frac{2}{2}[/tex] [tex]=[/tex][tex]\frac{18}{10}[/tex] ) Now we just have to add the two fractions. [tex]\frac{18}{10} + (-\frac{34}{10} ) = \frac{18}{10} -\frac{34}{10} = -\frac{16}{10}[/tex] . [tex]-\frac{16}{10}[/tex] can further be simplified into [tex]-\frac{8}{5}[/tex] .
