Simple, convert it to a decimal, first
move the decimal two places to the left
45%

0.45.
Then you change it into a fraction
45/100.
But, you can simplify it even more by dividing the numerator and denominator by 5.
45/5=9
and
100/5=20
Thus, it would be simplified, 9/20.
Ok,
divide by 2 on both sides...


So X = 3/8!
Where is the dot plot? Otherwise, the median is determined by finding out what is the middle number.
I'm guessing the "-ins" is "fifths". A fifth of 25 is 5 (25/5), so multiplying 5 by 4 will get you four-fifths. 20 students like football.
