How to Change Percentages to Decimals in Year 9 Math

Converting percentages to decimals is pretty simple! Here’s how to do it in just a few steps:

1. What is a Percentage?

   • A percentage is just a way to show a part of something out of 100.

2. How to Convert:

   • Step 1: Take off the percentage sign (%).
   • Step 2: Divide the number by 100.
   • Formula: If $x$ is the percentage, you find the decimal like this: $\text{Decimal} = \frac{x}{100}$

3. Examples:

   • If you have $25\%$: $25 \div 100 = 0.25$
   • If you have $50\%$: $50 \div 100 = 0.50$

This way of changing percentages makes it easy to understand how fractions, decimals, and percentages are all related!
