Hey there! :)
Let's change all the fractions and percents to decimal.
_____________________________________________________________
When changing fractions to decimal, divide the numerator by the denominator
When changing percents to decimal, remove the % sign and move the decimal to places to the left.
_____________________________________________________________
13 ÷ 20 = 0.65
66% = 0.66
195 ÷ 300 = 0.65
0.6500 = 0.65
_____________________________________________________________
The answer is 66% because it is the only one that isn't equivalent to 0.65
Hope this helps :)
