Study Notes
Finding a Percentage of a Number
- To find n% of x, multiply x by (n/100)
Percent Increase
- If a company has a 137% increase in production, it means they produced 137% more products in the second year compared to the first year
- To find the number of products produced in the second year, multiply the original number by (1 + 137/100)
Calculating Percentages
- 112% of $18 is calculated by multiplying $18 by (112/100)
- When the percentage is greater than 100, the result is greater than the original number
Dividing by 100 and Multiplying
- Dividing 20 by 100 gives 0.2, and multiplying it by 18 gives 3.6
Algorithm for Finding a Percentage
- The algorithm for finding the percentage of a number is: (part/whole) x 100
Meaning of 'Percent'

Discounted Product
- If a product is discounted by 30% and now costs $70, its original price was $100 (since $70 is 70% of $100)
Finding the Original Number
