Is 1/3 Bigger Than 2/3?

No, \(\frac{1}{3}\) < \(\frac{2}{3}\)

\(\frac{1}{3}\)
33.3333%
\(\frac{2}{3}\)
66.6667%

Method 1: Common Denominators

These fractions already share the same denominator: 3. We just need to compare the numerators.

Method 2: Cross Multiplication

A quicker way to compare fractions is to cross-multiply. Multiply each numerator by the other fraction's denominator:

Method 3: Decimal Comparison

Convert each fraction to a decimal by dividing the numerator by the denominator:

\(\frac{1}{3}\) as a decimal 0.333333
\(\frac{2}{3}\) as a decimal 0.666667
Difference 0.333333

Since 0.333333 is less than 0.666667, we confirm that \(\frac{1}{3} < \frac{2}{3}\). In percentage terms, \(\frac{1}{3}\) is 33.3333% and \(\frac{2}{3}\) is 66.6667%, a difference of 33.3333 percentage points.

Why Does This Work?

When two fractions share the same denominator, the pieces are the same size. A fraction with more pieces (a larger numerator) is simply a larger amount. Since 2 pieces is more than 1 pieces of the same size, \(\frac{2}{3}\) is the larger fraction.
