In a survey of 104 students, it was found that 79 went to the homecoming game this year

Using an example:

Suppose we had a big animal sanctuary for cats and dogs.

We had say 30 cats and 50 dogs

So by proportion we have:

#color(blue)("Using format type 1")#

#"cats : dogs " ->30:50->3:5# as ratio (proportions)

But for #3:5# we have 3 parts in combination with 5 parts giving a proportion total of #3+5=8#

Converting this to fractions and hence percentage

Cats
#=3/(3+5)=3/8 -> 3/8xx100% =color(white)("ddd") 37.5%" of the whole"# Dogs

#=5/(3+5)=5/8->5/8xx100% = color(white)("ddd")ul(62.5%" of the whole" #
