85793 - 36841 + 3826 = 48952 + 3826 = 52778

a,85793-36841+3826=52778

b,325,97+86,54+103,46=515,97

a) 52778

b) 515,97

1. Tính:

a) 85793 - 36841 + 3826

 = ( 85793 - 36841 ) + 3826

 = 48952 + 3826

 = 52778.

b) 325,97 + 86,54 + 103,46

 = 325,97 + ( 86,54 + 103,46)

 = 325,97 + 190

 = 515,97

\(\frac{84}{100}-\frac{29}{100}+\frac{30}{100}=\frac{85}{100}=\frac{17}{20}\)

85793-36841+3826=52778

325.97+86.54+103.46=515.97

+) = 17/20

+) = 53138

+) = 515,97

tk mk nha!

84/100 - 29/100 + 30/100=17/20

85793 - 36841 + 3826=53138

325,97 + 86,54 + 103,46=515,97
