Question

Find the lowest common denominator

Answer 1

 

Here, the denominators of the fractions are different (14 and 63). 

 

To make these unlike fractions in to like fractions, we need a common denominator. 

 

The least common denominator of 14 and 63 is 126. 

 

So, the fractions, 

 

[11/14] becomes [99/126] 

 

and [43/63] becomes [86/126] 

 

Now, [99/126] and [86/126] are like fractions. 

 

So, [99/126] + [86/126] = [(99 + 86)/126] 

 

= [185/126] 

 

So, [11/14] + [43/63] = [185/126]
