The figures on the top left and the bottom right have rotational symmetry.
So 9 students = 25% (100%-75%=25%)
100 : 25 = 4
4 * 9 =
36 students
It is located in quadrant 3. Hope this helped :D
Just remember BODMAS, which B= brackets O= Order D= Division M= Multiply A=Addition and S=Subtract
So first you solve the brackets so 44+22 is 66
So 66-4+12 so 66-4 is 62
62+12 is 74
So now you have got 74 divided by 2 which is 37
Hope this helps xx
