What is the common denominator of StartFraction 1 Over a EndFraction StartFraction 1 Over b EndFraction in the complex fraction
stepladder [879]

The common denominator is 1

Given the expression:

  • \frac{1/a-1/b}{1/a1/b}

Find the LCM of the numerator to have:

  • \dfrac{\frac{b-a}{ab} }{\frac{1}{a} \frac{1}{b} }

Simplify both the numerator and the denominator to have:

= \dfrac{\frac{b-a}{ab} }{\frac{1}{ab} }\\= \frac{b-a}{ab} \times ab\\=\frac{b-a}{1} \times 1  \\=\frac{b-a}{1}

From the result, we can see that the common denominator is 1
