Сократите дроби: 8/12, 4/8, 36/24, 21/20, 15/30, 60/48, 21/27, 21/28, 150/30, 12/15, 6/24, 30/24, 6/15, 3/15, 45/18.

Сократим каждую дробь на наибольший общий делитель числителя и знаменателя:

8/12 = 2/3; 4/8 = 1/2; 36/24 = 3/2; 21/20 — несократимая; 15/30 = 1/2; 60/48 = 5/4; 21/27 = 7/9; 21/28 = 3/4; 150/30 = 5; 12/15 = 4/5; 6/24 = 1/4; 30/24 = 5/4; 6/15 = 2/5; 3/15 = 1/5; 45/18 = 5/2.
