Question 981793
So there are 3 fractions 
{{{1/8}}}{{{2/5}}} and {{{ 3/10}}}
Numerator/Denominator

We need to add all these fractions together but to do that we need a common denominator.
40

So multiply each of the fractions by something to equal 40.

{{{1/8 * 5/5}}} and {{{2/5 * 8/8}}}and {{{3/10 * 4/4}}}
5/40, 16/40, and 12/40.
Add all these together to get
33/40 
Now {{{40/40 - 33/40}}}
We get 7/40

So 7/40ths of the surveyed chose winter.
7/40 of 200 is 35 people
Hope this helps.
