Simplify Fraction 12/18 to a Denominator of 6

Find what number you need to divide the original denominator by to get your target denominator. Here: 18 ÷ ? = 6, so ? = 3. Then divide both numerator and denominator by 3.

The target denominator must be a factor of the original denominator for this method to work. If 6 wasn't a factor of 18, you'd need to find equivalent fractions using multiplication instead.

Yes! $\frac{4}{6}$ can be simplified to $\frac{2}{3}$ by dividing both by 2. But since the question asks specifically for denominator 6, $\frac{4}{6}$ is the correct answer.

Cross-multiply to verify: $12 \times 6 = 72$ and $18 \times 4 = 72$. Since both products equal 72, the fractions are equivalent!

$\frac{5}{6}$ and $\frac{18}{6}$ are not equivalent to $\frac{12}{18}$. Use cross-multiplication to check: $12 \times 6 \neq 18 \times 5$ and $12 \times 6 \neq 18 \times 18$.
