Converting percentages into decimals is really useful when you need to do math! Here’s why it matters:

1. Making Math Easier: Changing a percentage to a decimal helps with calculations. For instance, if you want to find 25% of 80, you first change 25% into a decimal.

   • $25\%$ becomes $0.25$.
   • Now, multiply:
   • $0.25 \times 80 = 20$

2. Easier Calculations: Using decimals can make math tasks smoother. Let’s say you want to find 15% of 200.

   • First, turn 15% into a decimal:
   • $15\%$ is $0.15$.
   • Then, multiply:
   • $0.15 \times 200 = 30$

In short, turning percentages into decimals helps us do math faster and more accurately!
