The comparison between two quantities is known as ratios. It is generally expressed as a:b or a/b where a and b are two different quantities. On the other hand, the quotient of a given ratio that has two different quantities is known as rates. Here, the divisor is called the consequent and dividend is called the antecedent.
Rates and Ratios examples are commonly used to compare two different quantities.
1: There are 20 boys and 30 girls in a class. Express the ratio of the number of boys to that of girls.
Number of boys in the class = 20
Number of girls in the class = 30
Now, Ratio of boys to that of girls = 20:30 or 2:3.
2: Amrita buys a bag of 10 lb jelly beans that cost her $45. How much does 1lb of jelly bean cost?
Jelly Beans = 10 lb.
Cost of 10 lb jelly beans = $45.
Now, the cost of each jelly bean = $45 = 4500 cents.
So, 4500 / 10 = 450 / 1 i.e. equivalent to $4.50.
Hence, the cost of 1 lb jelly beans is $4.50.
