My favourite question on the problem solving sheet was question 3. I like this question because I haven't done one like this in a while and I liked how despite this, I still remembered how to do it properly. To solve this question and find out how many votes Sue received, you have to find out what how many votes Jim and Jane got. To do this you have to change the percents to actual numbers by reversing the way you would find percents.
To find Jim's number of votes you do 20% x 1000/100 = 200.
To find Jane's number of votes you do 45% x 1000/100= 450.
Then do 450 + 200 = 650.
Then do 1000-650= 350, so the number of votes Sue got was 350
To check, do 450+ 200+350= 1000
If you want to find out the percentage 350 you do 350/1000 x 100 = 35%
