1/7 plus 1/3 is 10/21, and 21 minus 10 is 11 so it's 11/21
We use one whole to take away 1/7 part and 1/3 part to find the remaining part which is shaded:

    [tex]1 - \dfrac{1}{7} - \dfrac{1}{3}[/tex]

Convert all the fractions to the same denominator, LCD being 21:
 [tex]= \dfrac{21}{21} - \dfrac{3}{21} - \dfrac{7}{21}[/tex]

Combine them:
[tex]= \dfrac{21-3-7}{21}[/tex]

Simplify them:
[tex]= \dfrac{11}{21}[/tex]

[tex]\boxed { \boxed {\text {Answer : } \dfrac{11}{21} \text { of the circle is shaded.}}}[/tex]
