Is 3/5 Bigger Than 4/5?

No, \(\frac{3}{5}\) < \(\frac{4}{5}\)

\(\frac{3}{5}\)
60%
\(\frac{4}{5}\)
80%

Method 1: Common Denominators

These fractions already share the same denominator: 5. 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:

\(\frac{3}{5}\) as a decimal 0.6
\(\frac{4}{5}\) as a decimal 0.8
Difference 0.2

Since 0.6 is less than 0.8, we confirm that \(\frac{3}{5} < \frac{4}{5}\). In percentage terms, \(\frac{3}{5}\) is 60% and \(\frac{4}{5}\) is 80%, a difference of 20 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 4 pieces is more than 3 pieces of the same size, \(\frac{4}{5}\) is the larger fraction.
