annamacsimava08 · Answer

(1 5/6 - 3/8) * х = 2 1/12х = 2 1/12 : (1 5/6 - 3/8)х = 2 1/12 : (1 20/24 - 9/24)х = 2 1/12 : 1 11/24х = 25/12 : 35/24х = 25/12 * 24/35х = 50/35 = 1 15/35х = 1 3/7(5/8 - 1/4) : х = 1/6х = (5/8 - 1/4) : 1/6х = (5/8 - 2/8) : 1/6х = 3/8 : 1/6х = 3/8 * 6 х = 18/8 = 2 2/8х = 2 1/4...
