Of the terms competing in the world archery championships, twenty percent are from Europe. Half as many as from the United States and one twentieth are from Africa. What fraction of teams are from neither Europe, the US or Africa.

13/20

15/20

13/15

17/20

Explanation:

Assume 100 total people.
20% of 100 = 20 --->Europeans
1/2 of 20 ---> 10 Americans
1/20 of 100 ---> 5 Africans
Now you would add them all up, and minus it by the total (100). 100 - 35= 65.
So, 65 people out of 100 are not EU, US or Africans. 65/100 is also equal to 13/20.
