First find GCF of the numbers:-
GCF of 2, 6 and 8 = 2
GCF od x^2 x and x is x
GCF of y^2, y^2 and y^3 is y^2
so the answer is 2xy^2
The third choice.
A ration is basically a fraction. It can be written different ways i.e. 2/3 or 2:3. They are both the same thing. There are 5 girls out of 39 students... ratio= 5/39 or 5:39
It will belong only irrational. Hope it help!
