Express 16 2/3 % (sixteen and two-thirds percent) as a fraction in simplest form.

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

a - base

b - exponent

so,

the base is 8the exponent is 3the exponent tells you to multiply 8 together three timesthe expanded form is 8*8*8
