Answer 1

So add all the numbers together

200 + 360 + 160 + 80 = 800
365/800

Answer 2

Take your graph, look at all the numbers add them together.
\[360+200+160+80=\dots\]\(=800\) people total surveyed.
According to the graph 360 out of 800 people like comedy.
\[\dfrac{360}{800}\Rightarrow \dfrac{9}{20}\]
I simplied \(\dfrac{360}{800}\) to \(\dfrac{9}{20}\).

Answer 3

so who should i give the medal to you both explained it and got the same answer

Answer 4

Narrowing it down
look for the GCF (greatest common factor)
they can't both be divided by 2 or 3, what about 4? Nope go to 5
So 365/5 = 73
800/5 160
so 73/160
those can both be divided by 8
so 9/20

Answer 5
