Step-by-step explanation:

we have

[tex]1\frac{3}{7} +10\frac{6}{7}[/tex]

step 1

Convert mixed number to an improper fraction

[tex]1\frac{3}{7}=\frac{1*7+3}{7}=\frac{10}{7}[/tex]  

[tex]10\frac{6}{7}=\frac{10*7+6}{7}=\frac{76}{7}[/tex]

step 2

Substitute in the expression above and find the sum

[tex]\frac{10}{7}+\frac{76}{7}=\frac{86}{7}[/tex]

Convert to mixed number

[tex]\frac{86}{7}=\frac{84}{7}+\frac{2}{7}=12\frac{2}{7}[/tex]
