Question

use number sense and fractions to help you

Answer 1

CNN=20/48=10/24=5/12
CBS=16/48=1/3=4/12
ABC=12/48=1/4=3/12
---------------------------------
12/12= 1

Answer 2

and what do you want? the percentage?

If so you just have the number of any individual favorite and divide it by the total.

So for CNN you would have 20/48
for CBS you would have 16/48
for ABC you would have 12/48

so that would be 41 & 2/3% (you take the decimal you get and multipy by 100)
for cbs it would be 33 & 1/3%
ABC would be 25%
