6 - 2, 43 = 3, 574 1/49, 75 = 1/49 + 75 = 49/49 + 75 = 124/49 = 2 (26/49)(4 1/2 - 2/55)15 = (9/2 - 2/55) 15 = (247/55 - 2/55) 15 = (245/55) 15 = (49/11) 3 = 3 * 3 = 9(9, 25 + 2, 04) = 9.25 + 2.04 = 11.29(4 1/5 - 3, 93) = (21/5 - 3.93) = (4.2 - 3.93) = 0.274,5 = 4.5
Therefore, the final expression is:3, 57: 2 (26/49), 9, 11.29(0.27) : 4.5
6 - 2, 43 = 3, 57
4 1/49, 75 = 1/49 + 75 = 49/49 + 75 = 124/49 = 2 (26/49)
(4 1/2 - 2/55)15 = (9/2 - 2/55) 15 = (247/55 - 2/55) 15 = (245/55) 15 = (49/11) 3 = 3 * 3 = 9
(9, 25 + 2, 04) = 9.25 + 2.04 = 11.29
(4 1/5 - 3, 93) = (21/5 - 3.93) = (4.2 - 3.93) = 0.27
4,5 = 4.5
Therefore, the final expression is:
3, 57: 2 (26/49), 9, 11.29(0.27) : 4.5
