Question

the parking lot of the mall has a capacity of 231 cars . O n sunday 3/11 of the parking lot was occupied with cars .how many additional number of cars could be parked there?

Answer 1

8/11 of the lot was unoccupied.  Thus, the # of add'l cars that could be parked there would be (8/11)(231 cars) = 168 (answer).

Answer 2

Hello!

3/11 was occupied. That means there's 8/11 left because 1 - 3/11 = 8/11

You have to find 8/11 of 231

$\frac{8}{11} \times \frac{231}{1} = \frac{1,848}{11} = 168$

$\framebox{168 additional cars could be parked there}$
