Hundredth — Definition, Formula & Examples

A hundredth is one of 100 equal parts of a whole. When you divide something into 100 equal pieces, each piece is one hundredth.

In the base-ten place value system, the hundredths place is the second digit to the right of the decimal point, representing a value of 1100\frac{1}{100} or 0.010.01 per unit in that position.

How It Works

The hundredths place sits two spots to the right of the decimal point. In the number 3.473.47, the digit 77 is in the hundredths place, so it stands for 77 hundredths, or 7100\frac{7}{100}. You can write any number of hundredths as a fraction with 100 on the bottom or as a two-digit decimal. For example, 2525 hundredths equals 25100\frac{25}{100}, which equals 0.250.25.

Worked Example

Problem: Write 63 hundredths as a fraction and as a decimal.
Write as a fraction: 63 hundredths means 63 out of 100 equal parts.
63100\frac{63}{100}
Write as a decimal: Since hundredths fill two decimal places, write 63 after the decimal point.
0.630.63
Answer: 63 hundredths = 63100\frac{63}{100} = 0.630.63

Why It Matters

Hundredths appear every time you work with money — pennies are hundredths of a dollar. Understanding this place value is also essential for measuring, reading percentages, and solving decimal problems throughout elementary and middle school math.

Common Mistakes

Mistake: Confusing tenths with hundredths by miscounting decimal places.
Correction: Tenths are the first digit after the decimal point; hundredths are the second. In 0.350.35, the 33 is tenths and the 55 is hundredths.
