Is 3/8 Bigger Than 5/8?

No, \(\frac{3}{8}\) < \(\frac{5}{8}\)

\(\frac{3}{8}\)
37.5%
\(\frac{5}{8}\)
62.5%

Method 1: Common Denominators

These fractions already share the same denominator: 8. 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:

\(\frac{3}{8}\) as a decimal 0.375
\(\frac{5}{8}\) as a decimal 0.625
Difference 0.25

Since 0.375 is less than 0.625, we confirm that \(\frac{3}{8} < \frac{5}{8}\). In percentage terms, \(\frac{3}{8}\) is 37.5% and \(\frac{5}{8}\) is 62.5%, a difference of 25 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 5 pieces is more than 3 pieces of the same size, \(\frac{5}{8}\) is the larger fraction.
