What is Ratio?
Ratio is defined as a relationship between two quantities, it is expressed one divided by the other.
What is percentage?
The percentage is defined as the ratio expressed as a fraction of 100.
The percentage is denoted by sign of %.
For example, if XYZ scored 46% marks in his test, it means that he scored 46 marks out of 100. It is written as 46/100 in the fraction form and 46:100 in terms of ratio.
Since a motor oil retailer needs to fill 50 one quart bottles, and he has two tanks: one that contains 12 gallons of oil and one that contains 2 gallons of oil, to determine which will need to fill the bottles,
the following calculation must be performed:
Quart to gallon = 4: 2
1/4 x 50 = X
50/4 = X
12.5 = X
X = 12.5
Therefore, the motor oil retailer needs 12.5 gallons of oil, so he will have to use both tanks, and still have 1 gallon of oil short.
