Jamie has seven tenths of a pound of chicken to cook for dinner if she is going to split the chicken between three people how much chicken will each person get

(7/10) / 3
3 can be written as 3/1 so we'll put that in there:
(7/10) / (3/1)
To divide fractions you flip the second one and multiply so it becomes:
7/10 * 1/3
7/30
Therefore, each person gets 7/30 of a pound of chicken.

Hope this helps :)
