Which fraction is equivalent to 0.16 the 6 is repeating<br>. Please show the work .
sergiy2304 [10]

Answer:

Answer is 1/6

Step-by-step explanation:

To convert  1/6 to decimal, just divide 1 by 6  

(That's what the fraction is showing; a fraction = numerator  ÷ denominator)  

1 ÷ 6 = 0.16666666 ...

So that is  1 6  in decimal form!

( 0.16 recurring)  

Note that per in percent means each and  perc e n t  means 100.

Therefore, percentage is just the quantity out of  100

! Simple!

So, multiply the decimal form of  

1 6  by  100

(That is why I did decimal first)

0.16666666 ...  ·(x) 100  =  16.66666 ... ... . %
