16 2/3 %
0.16666 (6 repeating forever) type it as a decimal
(also, from now on, just know that the 6 is repeating forever)
x = .1666 then you set that to equal x
10x= 1.666, 100x=16.66 and multiply by 10 and 100
100x-10x= 90x then subtract
16.66 - 1.66 = 15 do it again, but with the numbers
90x=15 now you set them to each other
x= 15/90 divide
x= 1/6 simplify
your answer is 1/6
