Tính:
a) \(985793 - 36841 + 3826 \);
b) \(\frac{84}{100} - \frac{29}{100} + \frac{30}{100}\) ;
c) \(325,97 + 86,54 + 103,46\).
a) \(85793 - 36841 + 3826 \)
\(= 48952 + 3826 = 52778\);
b) \(\frac{84}{100} - \frac{29}{100}+ \frac{30}{100} \)
\(=\frac{55}{100} + \frac{30}{100} =\frac{85}{100} = \frac{17}{20}\) ;
c) \(325,97 + 86,54 + 103,46\)
\(= 412,51 + 103,46 = 515,97\).
