Question

subtract: $\frac{1}{3}-\frac{1}{9}$
provide an answer as a simplified fraction or mixed number

Explanation:

Step1: Find a common denominator

The common - denominator of 3 and 9 is 9. Rewrite $\frac{1}{3}$ with a denominator of 9. Since $3\times3 = 9$, then $\frac{1}{3}=\frac{1\times3}{3\times3}=\frac{3}{9}$.

Step2: Subtract the fractions

Now we have $\frac{3}{9}-\frac{1}{9}=\frac{3 - 1}{9}$.

Step3: Calculate the numerator

$3−1 = 2$, so $\frac{3 - 1}{9}=\frac{2}{9}$.

Answer:

$\frac{2}{9}$
