1.2c 2.x 3.8ac 4 .2ac 5.12r...hope these answers are helpful to you..
Factorise the numerator
Factorise the denominator
What factors you common? It is that simple.
Question 1 4c/6c means 4xc/6xc
4 and c are factors at the top; 6 and c are factors at the bottom.
So, which is the common factor? c of course
Now do the rest
I will give a hand to do Question 5
Factorise the numerator. It gives -3 x r x -2 x 2 x s
factorise the denominator -3 x 3 x 2 x r x 2
Now, carefully pick up the common factors which are -3 and 2 and r
So, the answer is -6r
Hope you understand the process
Good luck

the answer for 1 & 2 is the following:
1. 2c
2. x
However for problem 3 I need to know if the bottom expression -4ac2 is C to the second power. the same question for problem 4 is it 12aC to the 5th power and in problem 5 is it -18r to the second power?
