Method 1: Common Denominators

To compare these fractions, we need a common denominator. The denominators are 7 and 8, and the least common denominator (LCD) is 56.

Step 1. Convert $\frac{6}{7}$: multiply numerator and denominator by 8. $\frac{6}{7} = \frac{6 \times 8}{7 \times 8} = \frac{48}{56}$
Step 2. Convert $\frac{3}{8}$: multiply numerator and denominator by 7. $\frac{3}{8} = \frac{3 \times 7}{8 \times 7} = \frac{21}{56}$
Step 3. Compare the numerators: 48 vs 21.
Step 4. Since 48 is greater than 21, we know that $\frac{6}{7} > \frac{3}{8}$.

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: $6 \times 8 = 48$.
Step 2. Multiply the numerator of the second fraction by the denominator of the first: $3 \times 7 = 21$.
Step 3. Compare the products: $48 > 21$, so $\frac{6}{7} > \frac{3}{8}$.

Method 3: Decimal Comparison

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

$\frac{6}{7}$ as a decimal 0.857143

$\frac{3}{8}$ as a decimal 0.375

Difference 0.482143

Since 0.857143 is greater than 0.375, we confirm that $\frac{6}{7} > \frac{3}{8}$. In percentage terms, $\frac{6}{7}$ is 85.7143% and $\frac{3}{8}$ is 37.5%, a difference of 48.2143 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 56, we're cutting both quantities into equal-sized pieces. Then 48 pieces vs 21 pieces is a straightforward comparison.
