Сократим дроби.

В дроби разложим числители и знаменатель на множители.

4/8 = 4 / (2 * 4) = 1 / (2 * 1) = 1/4; 9/36 = 9 / (4 * 9) = 1/4; 7/28 = 7 / (7 * 4) = 1/4; 5/35 = 5 / (5 * 7) = 1/7; 2/8 = 1/4; 8/24 = 1/3; 12/28 = 6/14 = 3/7; 45/100 = 9/20; 25/35 = 5/7; 45/54 = 5/6; 8/400 = 2/100 = 1/50; 32/256 = 16/128 = 8/64 = 1/8; 12/18 = 6/9 = 2/3; 20/24 = 5/6; 24/30 = 8/10 = 4/5; 56/49 = 8/7 = 1 1/7; 40/42 = 20/21; 48/36 = 8/6 = 4/3; 28/21 = 4/3.
