If 3 cars can hold 15 people how many cars are needed for 165. people. there is no pictures

3 cars hold 15 people so...
1 car holds 5 people.

Therefore...

33 cars hold 165 people.

To solve this problem, we can divide 165 people by 15 to start to find out how many cars there will be for 165 people. This is because this is a proportion. 165 divided by 15 is 11. Since 165:15 = 11, that means that C:3 = 11 too (with C being the number of cars for 165 people). If C:3 = 11, we can multiply each side by 3 to figure out the C is equal to 33 (we multiply by 3 to get rid of the denominator, since the : sign means to divide). That means that 33 cars will be needed for 165 people.
