(1 3/5 + 2,2) : 6 1/3 = (1,6 + 2,2) : 19/3 = 3,8 * 3/19 = 38/10 * 3/19 =
= 2/10 * 3 = 6/10 = 0,6
(3 4/7 + 11/14) * 3,5 = (3 8/14 + 11/14) * 3,5 = 3 19/14 * 3,5 = 4 5/14 * 3,5 =
= 61/14 * 35/10 = 2135/140 = 15 35/140 = 15 1/4 = 15,25
(1 - 0,125 - 5/6)/(0,25)² = ( 0,875 - 5/6)/(0,25)² = (35/40 - 5/6)/(0,25)² =
= (7/8 - 5/6)/(0,25)² = (21/24 - 20/24)/(0,25)² = 1/24 : (1/4)² =
= 1/24 : 1/16 = 1/24 * 16 = 1/3 * 2 = 2/3
