🔄 What Is a Decimal?

A decimal is a way to write numbers that aren't whole. It uses a decimal point to separate the whole part from the fractional part. For example:

• 0.5 means 5 tenths
• 2.75 means 2 and 75 hundredths

Decimals are part of our everyday number system — used in prices, measurements, and data.

🎯 What Is a Percent?

Percent means "per hundred." It's another way to show part of a whole. The symbol % stands for percent.

• 25% means 25 out of 100
• 50% means half
• 100% means the whole

Percents are everywhere — from discounts at the store to battery life on your phone.
