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

  1. Always write the percentage over 100: This is the first step to convert it into a fraction.
  2. 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.
  3. 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}
