Question

On a ship the ratio of crew members to passengers is 1:15. There are 540 passengers. How many crew members are there?​

Answer 1

Answer: 36

Step-by-step explanation: Keep multiplying 15 until you get 540. 36 * 15 is 540

Answer 2

36 Crew members

Explanation:

Divide 540 by 15, to find how much the new amount of passengers had increased. It should be 36.

Now to keep the ration even, you need to multiply the amount of Crew members by 36 too.

Double checking your answer:

1/15=0.06666666667...

36/540=0.06666666667...

There's probably other ways to solve this, this is just how I did it.
