Introduction to Percentages
Hello, Year 6! Today, we’re going to learn about percentages and how we can turn them into fractions. Understanding percentages as fractions is a useful skill that helps us in many real-life situations, like shopping, cooking, and even sports!
What is a Percentage?
A percentage means “out of 100.” For example, if you say 25%, it means 25 out of every 100. It’s a way to compare things easily.
Converting Percentages to Fractions
Step 1: Write the Percentage as a Fraction
To convert a percentage to a fraction, you write it over 100. For example:
- 25% = \frac{25}{100}
Step 2: Simplify the Fraction
Next, we simplify the fraction if possible. This means we make the fraction smaller while keeping it equal.
For example:
- 25% = \frac{25}{100}
- Both numbers can be divided by 25:\frac{25 \div 25}{100 \div 25} = \frac{1}{4}
So, 25% is the same as \frac{1}{4}
Key Rules and Tips
- Always write the percentage over 100: This is the first step to convert it into a fraction.
- Look for the greatest common divisor (GCD): This helps you simplify the fraction. It’s the biggest number that can divide both the numerator and denominator.
- Check if your fraction can be simplified: Not all fractions can be simplified, but many can!
Examples
- Example 1: Convert 50% to a fraction.50% = \frac{50}{100} = \frac{1}{2}
- Example 2: Convert 10% to a fraction.10% = \frac{10}{100} = \frac{1}{10}
- Example 3: Convert 75% to a fraction.75% = \frac{75}{100} = \frac{3}{4}
