Is 1/4 Bigger Than 4/11?

Method 1: Common Denominators

To compare these fractions, we need a common denominator. The denominators are 4 and 11, and the least common denominator (LCD) is 44.

• Step 1. Convert \(\frac{1}{4}\): multiply numerator and denominator by 11.
  \[\frac{1}{4} = \frac{1 \times 11}{4 \times 11} = \frac{11}{44}\]
• Step 2. Convert \(\frac{4}{11}\): multiply numerator and denominator by 4.
  \[\frac{4}{11} = \frac{4 \times 4}{11 \times 4} = \frac{16}{44}\]
• Step 3. Compare the numerators: 11 vs 16.
• Step 4. Since 11 is less than 16, we know that \(\frac{1}{4} < \frac{4}{11}\).

Method 2: Cross Multiplication

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

• Step 1. Multiply the numerator of the first fraction by the denominator of the second: \(1 \times 11 = 11\).
• Step 2. Multiply the numerator of the second fraction by the denominator of the first: \(4 \times 4 = 16\).
• Step 3. Compare the products: \(11 < 16\), so \(\frac{1}{4} < \frac{4}{11}\).

Method 3: Decimal Comparison

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

Since 0.25 is less than 0.363636, we confirm that \(\frac{1}{4} < \frac{4}{11}\). In percentage terms, \(\frac{1}{4}\) is 25% and \(\frac{4}{11}\) is 36.3636%, a difference of 11.3636 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 44, we're cutting both quantities into equal-sized pieces. Then 11 pieces vs 16 pieces is a straightforward comparison.
