Answer:
10
Step-by-step explanation:
The least common denominator can be found by finding the LCM of the 2 denominators:
First let's list the multiples of the first denominator :
10,20,30,40,50
Now let's list the multiples of the second denominator :
5,10,15,20,25
As we can see the lowest number that appears in both lists is 10.
Therefore 10 is the least common denominator.
