It would be 9/25. First you find the common denominator which is 25 so then you convert 1/5 to 5/25 so now you have 4/25+5/25 which you would get 9/25 and since 9 can only be divided be 3 and 25 can't your answer would be 9/25.
The GCF is 3*b = 3b
Step-by-step explanation:
The GCF is the Greatest Common Factor which will divide all the numbers whose GCF it is.
To find the GCF, we factorize the polynomials first
So,

We can see that only 3 and b are common in factors of both polynomials
So,
The GCF is 3*b = 3b
