Answer:
x^(7/5)
Step-by-step explanation:
Root goes on bottom of fraction
Power goes on top
x^(7/5)
5 out of 20 like Star Wars so what value (x) should like Star Wars out of 200. Set up a proportion comparing the two.
x= # of people in 7th gr who like Star Wars
5/20= x/200
cross multiply
(5*200)= (20*x)
1000= 20x
divide both sides by 20
50= x
ANSWER: 50 people in the 7th grade should like Star Wars.
