You eat one slice of a pizza that is cut into 8 even slices. what is the amount you ate written as a decimal

In order to change a fraction into a decimal you must divide the numerator by the decimal so divide 1 by 8 and so as you go through the equation you get a decimal number because 8 cannot go into 1 of course. 

0.125 is the amount you ate in decimal form 

X=3 and y=4 is the answer

It is blindness and randomization
