Decimals to Fractions, page 187

A decimal shows numbers less than one. It also represents values between whole numbers using a decimal point. The digits after the point represent parts of a whole. They can be in tenths, hundredths, etc.

A fraction represents a part of a whole. It has two numbers: a numerator (top number) and a denominator (bottom number). The numerator shows how many parts we have. The denominator shows how many parts make up the whole.
