Ratios are used to compare values. They tell us how much of one thing there is compared to another. For example, ratios can be used to compare the number of girl puppies to boy puppies that were born. If we have a total of six puppies, where two are girls and four are boys, we can write that in ratio form as 2:4 (girls:boys). We can also write it in factor form as 2/4. To compare the number of boy puppies to girl puppies, we can simply rewrite our ratio with the number of boys first as 4:2 (boys:girls) or 4/2.

Proportions are related to ratios in that they tell you when two ratios are equal to each other. Let's see how proportions work for our puppies. Our first ratio of girls to boys is 2:4 for our litter of six. If our next litter had a ratio of 4:8 of girls to boys, it would be proportional to our first litter; because if we divide each of our ratios, we will find that they are equal: 2 / 4 = 0.5 and 4 / 8 = 0.5, as well. My ratios are proportional if they divide into same number.

Answer:
- A ratio is a comparison of two or more numbers that indicate their relative magnitudes.
- A ratio compares two quantities by division
- The ratio can be specified either by specifying both base numbers written as "a to b" or "a:b", or by specifying only the value of their quotient a/b
- For example, the ratio 2 : 7 is also represented as 2/7, where 2 is the antecedent and 7 is the consequence.
- Ratios in everyday life: The car was going 60 miles per hour or 60 miles in 1 hour.
Application of ratios:
- Ratios are used when converting from one currency to another. For example, you can convert pounds to euros or dollars using ratios.
- Bet winnings are calculated using a ratio.
