a) 85793 - 36841 + 3826
= 48952 + 3826
= 52778

b) \(\frac{84}{100}\) - \(\frac{29}{100}\) + \(\frac{30}{100}\)
= \(\frac{84 - 29}{100}\) + \(\frac{30}{100}\)
= \(\frac{55}{100}\) + \(\frac{30}{100}\)
= \(\frac{55 + 30}{100}\)
= \(\frac{85}{100}\)

c) 325,97 + 86,54 + 103,46
= 412,51 + 103,46
= 515,97
