Fractions and Decimals
Different ways to show parts of a whole, like splitting a pizza or measuring ingredients for a recipe đą
Kurze EinfĂŒhrung
Fractions and decimals are two ways to represent parts of something whole. Just like cutting a chocolate bar into pieces or measuring water in a bottle, these numbers help us work with quantities that aren't whole numbers. They're essential tools we use daily, from cooking and shopping to sharing things fairly with friends.

Understanding Fractions đ
A fraction shows how many parts we're talking about out of a total. Like a pizza cut into 8 slices - if you eat 3 slices, that's 3/8 of the pizza. The bottom number (denominator) shows the total parts, and the top number (numerator) shows how many parts we're using.
Understanding Decimals đ
Decimals are another way to show parts of a whole, using a dot (decimal point). It's like money - $1.50 means one dollar and fifty cents, or one and a half dollars. Decimals are based on tens, hundreds, and thousands, just like our normal counting system.
Converting Between Forms âïž
Fractions and decimals can show the same amount in different ways. Half can be written as 1/2 or 0.5, quarter as 1/4 or 0.25. It's like having different languages to express the same thing - you might say 'half a pizza' or '0.5 of a pizza.'
Beispiele
- When baking cookies đȘ, a recipe might call for 3/4 cup of sugar or 0.75 cups - they mean exactly the same amount
- In sports âœ, if a team wins 75% of their games, that's the same as winning 3/4 or 0.75 of their total games
- When filling a water bottle đ„€, half-full can be written as 1/2 or 0.5 - both tell you the same thing about how much water is in the bottle
