Answer:
[tex]\frac{1}{18}[/tex]
Step-by-step explanation:
To find the missing portion you need to do:
[tex]1-\frac{1}{4}-\frac{1}{3}-\frac{1}{6}-\frac{1}{9}-\frac{1}{12}[/tex]
Which is, if you put them all to the same denominator:
[tex]\frac{36}{36}-\frac{9}{36}-\frac{12}{36}-\frac{6}{36}-\frac{4}{36}-\frac{3}{36}[/tex]
Which is:
[tex]\frac{36-9-12-6-4-3}{36}[/tex]
Which is:
[tex]\frac{2}{36}[/tex], which is, simplified, [tex]\frac{1}{18}[/tex]
Hope this helps :)
