Answer: I'm guessing 72

Step-by-step explanation:

its says 8 to 5. If you read it correctly you will know that 8 is the number of passengers and 5 is the number of cargo. 45 : 5 = 9 x 8 = 72

Monty · Answer 2

72 passenger planes

Step-by-step explanation:

ratio passenger to cargo = 8 to 5 = 8/5

Let p = number of passenger planes.

The ratio of passenger to cargo planes that actually landed is p/45.

The ratio in general is 8/5, so 8/5 must equal p/45.

p/45 = 8/5

5p = 45 * 8

p = 9 * 8

p = 72
