Answer:
Step-by-step explanation:
To find the GCF we factor all the given terms and then find the Greatest Common Factor from both ,
So , The given two terms can be given by

Here common numbers that are in both are
2.7.c.c.d
so GCF= 
3.1 is like a example when it is hiding a zero behind it and you find this when you do a math problem and you don't put zero in front of a number like 100-89 you don't write "011" so that is why it is like that
Let x=3.77777777...
10x=37.777777777...
9x=10x-x=34
9x=34 so x=34/9=3 7/9
Answer:
