Is 4/5 Bigger Than 9/11?

No, \(\frac{4}{5}\) < \(\frac{9}{11}\)

\(\frac{4}{5}\)
80%
\(\frac{9}{11}\)
81.8182%

Method 1: Common Denominators

To compare these fractions, we need a common denominator. The denominators are 5 and 11, and the least common denominator (LCD) is 55.

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:

\(\frac{4}{5}\) as a decimal 0.8
\(\frac{9}{11}\) as a decimal 0.818182
Difference 0.018182

Since 0.8 is less than 0.818182, we confirm that \(\frac{4}{5} < \frac{9}{11}\). In percentage terms, \(\frac{4}{5}\) is 80% and \(\frac{9}{11}\) is 81.8182%, a difference of 1.8182 percentage points.

Why Does This Work?

These fractions have different numerators and different denominators, so we can't compare them directly. By converting to a common denominator of 55, we're cutting both quantities into equal-sized pieces. Then 44 pieces vs 45 pieces is a straightforward comparison.
