Question

(3/7х - 5/6) * (1 2/33) =2.5

Answer 1

(3/7х - 5/6) * (1 2/33) =2.5
3/7 х - 5/6 = 2,5 : 1_2/33
3/7 х - 5/6 = 25/10 : 35/33
3/7 х - 5/6 = 5/2 * 33/35
3/7 х  - 5/6 = (5*33) / (2*35)
3/7 х - 5/6 = 33 / 14
3/7 х = 33/14 + 5/6
3/ 7 х = 2_5/14 + 5/6 
3/7 х = 2_15/42 + 35/42
3/7 х = 2_50/42
3/7 х = 3_8/42
3/7 х = 3_4/21
х = 3_4/21 : 3/7
х= 67 / 21 * 7/3
х= (67*7) / (21*3)
х= 67/9
х=7_4/9
