PROBLEM SOLVING #2

Once again we have recieved another problem solving worksheet. They're actually really fun. The questions are chalenging and you feel smarter when you solve them. My favourite question this week was the following:

The pie chart shows a percentage breakdown of 1000 votes in a student election. How many votes did Sue receive?

okay so this question is super easy isnt it.
I know, IT IS!
but you know what.
when i first looked at this question i was confused! I dont know, why or how i was confused, but i was. I had to read it like 5 times to understand and then it clicked. wow. embarassing.
but anyways.
this is how you solve it.

there are 1000 votes.
45% of the votes went to jane
20% of the votes went to jim
and sue?

okay well.
out of 100%, Jane and Jim got 65% of the votes.
therefore. 35% of 1000 votes went to sue.
now. take thirty five per cent.
which means 35 per one hundred.
SOOO 35% of 1000 is 35.

BUT . we're dealing with 1000.
soooo 1000 is 100 ^ 10 correct?
THEREFORE. if you multiply 35 by 10, you will get the answer.
so the answer is 350
YAY.


that was the long way.
there are other ways to solve this question.
you could multiply .35 by 1000 which also gives you 350
OR .
find out how many votes the Jane and Jim got.
(1000 - (.20^1000)-(.45^1000)) which gives you 650
then just subtract that from 1000
which gives you 350.

so many ways to solve one question.
