first, to add fractions, we need both with the same denominator. to change it we can multiply or divide the numerator and the denominator of a fraction.
in this case for example we can multiply each part of the fraction 14/3 by 2
[tex]\frac{14\cdot2}{3\cdot2}=\frac{28}{6}[/tex]and now we can add
[tex]\frac{28}{6}+\frac{5}{6}=\frac{33}{6}[/tex]and finally, we can simplify dividing 33 and 6 by 3
[tex]\frac{\frac{33}{3}}{\frac{6}{3}}=\frac{11}{2}[/tex]So the answer is: 11/2
