17.5 - 3 4/9 3.5 = 17.5 - (31/9) 3.517.5 - (31/9) 3.5 = 17.5 - (31 3.5 / 9)17.5 - (31 * 3.5 / 9) = 17.5 - (108.5 / 9)17.5 - (108.5 / 9) = 17.5 - 12.0517.5 - 12.05 = 5.45
Therefore, 17.5 - 3 4/9 * 3.5 = 5.45.
17.5 - 3 4/9 3.5 = 17.5 - (31/9) 3.5
17.5 - (31/9) 3.5 = 17.5 - (31 3.5 / 9)
17.5 - (31 * 3.5 / 9) = 17.5 - (108.5 / 9)
17.5 - (108.5 / 9) = 17.5 - 12.05
17.5 - 12.05 = 5.45
Therefore, 17.5 - 3 4/9 * 3.5 = 5.45.
