1) Half of the pupils choose Math -- True; the Math area is one-half the area of the circle.

Most of the pupils really like their school -- Can't say; that's not part of the picture.

More pupils chose Science than PE -- False; the area for science is smaller than the area for PE.

How many students did not choose Science or PE -- 10; 20 chose Math; half of that chose PE (10) and

the remaining area is the same size as that for PE.

2) a) The "Men" section is one-fourth of the circle = 25%

b) The "Children" section is a little more than one-half = 55%

c) The "Women" section is more than one-fourth (25%) but not really close to one half (50%) = 35%.

Or, another way, it's a little more than one-third of the circle.
