Answer:
77
Step-by-step explanation:
b is present in both ratios, find first the LCM of 8 and 6, which is 24.
Multiply a:b=3:8 by 3 to get a:b=9:24
Similarly, multiply b:c=6:11 by 4 to get b:c=24:44
Then we conclude
a:b:c=9:24:44
Since there is no common factor among the three numbers, this is the simplest ratio possible.
If a,b and c are integers, the smallest values for a,b and c are 9,24,44.
Add up the three numbers to get the least value of a+b+c=77.
