Answer:
8/21 part
Step-by-step explanation:
Given that,
A franchise is owned by three people. The first owns 1/3 of the business and the second owns 2/7 of the business.
We need to find the fractional part of the business is owned by the third person. It can be calculated as follows :
[tex]x=1-(\dfrac{1}{3}+\dfrac{2}{7})\\\\x=1-\dfrac{13}{21}\\\\x=\dfrac{8}{21}[/tex]
Hence, 8/21 part of the business is owned by the third person.
