Finding a Percent of a Number
Finding a Percent of a Number is a skill on Pengi from Lesson 11: Percents in Saxon Math, Course 3.
Key Concepts
Property Forty percent of the 30 students rode the bus. To find the number of students, convert the percent to a fraction and find that fractional part of the total: $\frac{2}{5} \text{ of } 30 = 12$.
Examples Find 25% of 44: First, $25\% = \frac{1}{4}$. Then, $\frac{1}{4} \cdot 44 = 11$. A tablet that costs 500 dollars is 30% off. The discount is: $30\% = \frac{3}{10}$. So, $\frac{3}{10} \cdot 500 = 150$ dollars off. 60% of the 15 players scored. That means: $60\% = \frac{3}{5}$. So, $\frac{3}{5} \cdot 15 = 9$ players scored.
Explanation What does "20% of 50" even mean? It's just a math mission where 'of' is code for 'multiply.' Your first step is to convert the percent to its fraction disguise (20% becomes $\frac{1}{5}$). Then, you multiply that fraction by the number. You're simply calculating a specific slice of the whole number pie!
