Reference Guide

Tenths

One whole divided into 10 equal parts gives tenths. Each part is one tenth, written as 0.1.

0.1 = \frac{1}{10}

Shading 3 parts out of 10 means three tenths, or 0.3. The digit after the decimal point tells you how many tenths.

Hundredths

A 10 × 10 grid has 100 equal squares. Each square is one hundredth, written as 0.01.

0.01 = \frac{1}{100}

Shading 25 squares means twenty-five hundredths, or 0.25. Notice that one full column (10 squares) equals one tenth.

Decimals and Fractions

Every decimal can be written as a fraction. The number of decimal places tells you the denominator.

0.75 = \frac{75}{100} = \frac{3}{4}

Simplify by dividing the numerator and denominator by their greatest common factor. Here, 75 and 100 share a factor of 25.

Comparing Decimals

To compare two decimals, look at the digits from left to right. The first place where they differ tells you which is larger.

0.45 > 0.3 \quad \text{because } 45 > 30 \text{ hundredths}

Using grids makes this visual. The decimal with more shaded cells is the larger number.
