Question

What is the best choice for the common denominator in this problem.

Answer 1

Given:-

`(1)/(5)+(2)/(6)`

To find the required value.

So to add the given fraction. first we should have same denominator. so we take LCM,

`\text{LCM of 5 and 6 is 30.}`

So we get,

`(1)/(5)+(2)/(6)=(1*6)/(5*6)+(2*5)/(6*5)=(6)/(30)+(10)/(30)=(16)/(30)`

So the correct denominator is 30.
