Answer:
Option (c) is correct.
least common common denominator is 60.
Step-by-step explanation:
Given numbers are
We have to find the least common denominator for the given numbers.
least common number is the greatest value that is multiple of all the given numbers.
Since, denominator of given fractional numbers are 3, ,4 ,5
So least common denominator is the number that is multiple of all the given denominator.
Since, 3 = 3 × 1
4 = 2 × 2
5 = 5 × 1
Least common number is find by multiplying all the factors and taking common factor one time.Since, 3, 4, 5 do not have any factor in common
So, the product of 3, 4, 5 are the least common denominator
thus, 3 × 4 × 5 = 60
Thus, least common common denominator is 60.
