Step-by-step explanation:
Take The fractions and put them into a common denominator
[tex]\frac{2}{5}+ \frac{3}{4}+ 1\frac{1}{10}[/tex]
[tex]\frac{16}{40}+ \frac{30}{40}+ 1\frac{4}{40}[/tex]
make the right fraction improper to make it easier to add
[tex]\frac{16}{40}+ \frac{30}{40}+ \frac{44}{40}[/tex]
add
[tex]\frac{46}{40}+ \frac{44}{40}[/tex]
[tex]\frac{90}{40}[/tex]
Make it into a mixed fraction again
[tex]2\frac{10}{40}[/tex]
Simplify the fraction.
[tex]2 \frac{1}{4}[/tex]
