Answer:

232 lifeboats are needed for a cruise ship containing 2,315 people.

Explanation:

A small ship can hold 463 people.

A cargo ship can hold 8,583 people

A cruise ship can hold unknown people

A battle ship can hold 17,402 people

To find the unknown:

If a cruise ship can hold 5 times the amount of people on a small ship. You must do 463 × 5 = 2,315. Therefore, a cruise ship can hold 2,315 people.

To find out how many lifeboats a cruise ship needs:

Put the numbers into a ratio. If there needs to be 1 lifeboat for every 10 passengers the ratio is 1 : 10. Substitute the values into a ratio, for every 2,315 passengers there must be unknown lifeboats.

1 : 10

? : 2,315

Must do 2,315 ÷ 10 = 232 (rounded answer) [231.5]

(YOU MUST ROUND THE ANSWER UP TO GET A WHOLE NUMBER BECAUSE IN THESE TYPES OF QUESTION YOU CANNOT HAVE A DECIMAL)

So 232 lifeboats are needed for a cruise ship containing 2,315 people.
