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

5/6v+10=5 what is the answer
yulyashka [42]

Answer:

x= -3/2

Step-by-step explanation:

You would multiply both sides by 6x+10 and then that would give you 5-5)6x+10) and you would divide both sides by 5. This would give you 1=6x+10, you would then try to isolate the 6x giving you -6x=10-1  or -6x=9 and you would see if the solutions are in the defined ranges so x=-5/3 is NOT in the defined range but x=-3/2 is.
