This should help u get it Ratios are used to compare amounts or quantities or describe a relationship between two amounts or quantities. For example, a ratio might be used to describe the cost of a month’s rent as compared to the income earned in one month. You may also use a ratio to compare the number of elephants to the total number of animals in a zoo, or the amount of calories per serving in two different brands of ice cream. Rates are a special type of ratio used to describe a relationship between different units of measure, such as speed, wages, or prices. A car can be described as traveling 60 miles per hour; a landscaper might earn $35 per lawn mowed; gas may be sold at $3 per gallon. RatiosRatios compare quantities using division. This means that you can set up a ratio between two quantities as a division expression between those same two quantities. Here is an example. If you have a platter containing 10 sugar cookies and 20 chocolate chip cookies, you can compare the cookies using a ratio. The ratio of sugar cookies to chocolate chip cookies is: 
 The ratio of chocolate chip cookies to sugar cookies is: 
   You can write the ratio using words, a fraction, and also using a colon as shown below. ratio of sugar cookies tochocolate chip cookies10 to 20
10 : 20 Some people think about this ratio as: “For every 10 sugar cookies I have, I have 20 chocolate chip cookies.” You can also simplify the ratio just as you simplify a fraction.
  So we can also say that: ratio of sugar cookies tochocolate chip cookies1 to 2
1 : 2
