Hey everyone, I am having trouble with knowing when to take the reciprocal...so I would greatly appreciate any insight....
A total of n trucks and cars are parked in a lot. If the number of cars is 1/4 the number of trucks, and 2/3 of the trucks are pickups, how many pickups, in terms of n, are parked in the lot?
Answer: 8/15n
A similar problem with taking the reciprocal is:
At a certain pizzeria, 1/8 of the pizzas sold in one week were mushroom and 1/3 of the remaining pizzas sold were pepperoni. If n of the pizzas sold were pepperoni, how many were mushroom?
Answer: 3/7n
Thank you!
