How to Compare $\frac{8}{9}$ and $\frac{7}{10}$ Step by Step

Wondering how to figure out which fraction is bigger without a calculator? Comparing $\frac{8}{9}$ and $\frac{7}{10}$ is straightforward once you know the right approach. Below we walk through three proven methods for comparing fractions: finding a common denominator, cross multiplication, and converting to decimals. Each method will give you the same answer, so choose the one that feels easiest.

Method 1: Common Denominators

To compare these fractions, we need a common denominator. The denominators are 9 and 10, and the least common denominator (LCD) is 90.

Step 1. Convert $\frac{8}{9}$: multiply numerator and denominator by 10. $\frac{8}{9} = \frac{8 \times 10}{9 \times 10} = \frac{80}{90}$
Step 2. Convert $\frac{7}{10}$: multiply numerator and denominator by 9. $\frac{7}{10} = \frac{7 \times 9}{10 \times 9} = \frac{63}{90}$
Step 3. Compare the numerators: 80 vs 63.
Step 4. Since 80 is greater than 63, we know that $\frac{8}{9} > \frac{7}{10}$.

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: $8 \times 10 = 80$.
Step 2. Multiply the numerator of the second fraction by the denominator of the first: $7 \times 9 = 63$.
Step 3. Compare the products: $80 > 63$, so $\frac{8}{9} > \frac{7}{10}$.

Method 3: Decimal Comparison

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

$\frac{8}{9}$ as a decimal 0.888889

$\frac{7}{10}$ as a decimal 0.7

Difference 0.188889

Since 0.888889 is greater than 0.7, we confirm that $\frac{8}{9} > \frac{7}{10}$. In percentage terms, $\frac{8}{9}$ is 88.8889% and $\frac{7}{10}$ is 70%, a difference of 18.8889 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 90, we're cutting both quantities into equal-sized pieces. Then 80 pieces vs 63 pieces is a straightforward comparison.
