In mathematics, a percentage is a method of representing numbers as a fraction of 100 (percent meaning "per hundred"). percentage is represented as percent sign, "%".
percentage is represented as percent sign, "%".
How to solve percentage problems:
Some Rules:
1)When we compare two quantities of the same kind by division, we have a ratio of those two quantities.
2) The ratio should be in the lowest form.
3) The order in the ratio is very important. It cannot be interchanged.
4) Ratio has no unit.
5) Two or more ratios can be compared
6) Proportion is an equality of two ratios.
A Percentage problem :
The speed of a car is 60km per hour. If it is increased by 10% find the new speed of the car.
Solution:
Speed of car = 60km
Increased percentage =10 % of 60km
= (10 / 100) × (60) =6km
New speed =60 + 6 = 66km
