A ratio is a division of two quantities that may or may not be of the same nature.

Same nature
You can for example have the ratio of the perimeters of two similar triangles. ratio=perimeter1/perimeter2

Different nature
:
If an automobilist travels at a constant rate (notice the root RATE, RATIO), the rate of travel is expressed as the ratio of the distance travelled (d) to the time taken to travel the distance. That ratio is called the speed v
v=d/t
Since the ratio involves two quantities of different nature, the speed has a unit derived from the unit of distance and the unit of time; Example v=65 km/h

Other examples:
There is a ratio of 1.45 US $ to 1 Euro. This is usually referred to as the exchange RATE.
The odds of something happening is 7 to 2.

What is really meant when a ratio is involved depends on the context. But what you should remember is that a ratio involves the division of two quantities.
Proportions: The equality of two ratios is called a proprtion.

Please explain how you do ratios


A ratio can be simplified by dividing both sides of the ratio by the Highest Common Factor (HCF). The highest common factor is the largest number that goes into both numbers of your ratio. In example 1 you are asked to simplify the ratio 6:8. Here the HCF is 2 so divide both sides of the ratio by 2 to give 3:4.

Do you mean 8:1000 as a ratio?

8:1000 can also be written as 8 / 1000

This can be reduced by dividing both sides by 8

8 / 8 = 1
1000 / 8 = 125

8:1000 = 1:125

ratio: a comparative value. "so many pounds to ounces"
i.e. 3 to 1
proportion: a part of the original. a percentage of the whole.
i.e.: a proportional band of a thermostat. that "dead zone" between the set point and the desired point is 10 degrees.
