Najpierw obliczmy wartości a i b:
a = (3 1/3 + 3) : 2 - 1/6 = 6 1/3 : 2 - 1/6 = 6 2/6 : 2 - 1/6 = 3 1/6 - 1/6 = 3
b = 3 1/3 + ( 3 : 2 - 1/6 ) = 3 1/3 + (3/2 - 1/6) = 3 1/3 + (9/6 - 1/6) = 3 1/3 + 8/6 = 3 2/6 + 8/6 = 20/6 + 8/6 = 28/6 = 4 4/6 = 4 2/3
75% z 3:
3 * 0,75 = 3/1 * 75/100 = 225/100 = 2,25
45% z 4 2/3:
14/3 * 0,45 = 14/3 * 45/100 = 14/1 * 15/100 = 210/100 = 2,1
2,25 > 2,1
75% z 3 jest większe od 45% z 4 2/3
