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
