9/8x(4i6/10-2i14/10)+(1/2x1/2x1/2)= 9/8 * (4 6/10 - 2 14/10) + (1/2 * 1/2 * 1/2) = 9/8 * (46/10 - 34/10) + 1/8 = (9/8 * 12/10) + 1/8 = 108/80 + 1/8 = 108/80 + 10/80 = 118/80 = 1 38/80

9/8x(4i6/10-2i14/10)+(1/2x1/2x1/2)= 9/8 * ( 46/10 - 34/10 ) + 0,125 = 9/8 * 12/10 + 0,125 = 27/20 + 0,125 = 1,35 + 0,125 = 1,475
