Idon't understand ratios. will someone explain them?

Ratios are like fractions. 5:6 is the same as 5/6.

A ratio says how much of one thing there is compared to another thing.

Example. Say if there 4 apples and 3 blueberries 

The ratio to apples to berries will be 4:3

But if its blueberries to apples it would be 3:4

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
