Fractions: Parts of a Whole

Fractions show parts of things, like half a pizza (\(\frac{1}{2}\)) or three-fourths of a cake (\(\frac{3}{4}\)).

• Numerator (top number): parts you have
• Denominator (bottom number): total parts

Decimals: Another Way to Show Parts

Decimals are another way to write fractions, especially tenths and hundredths. For example, 0.5 is the same as \(\frac{1}{2}\).
