Question

Tính:

a) 85793 \(-\) 36841 \(+\) 3826;

b) \(\dfrac{84}{100}-\dfrac{29}{100}+\dfrac{30}{100}\);

c) 325,97 \(+\) 86,54 \(+\) 103,46.

Answer 1

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

b) \(\dfrac{84}{100}-\dfrac{29}{100}+\dfrac{30}{100}\) =  \(\dfrac{55}{100}+\dfrac{30}{100}\) = \(\dfrac{85}{100}\) =\(\dfrac{17}{20}\) 

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

Answer 2

a)\(85793-36841+3826=52778\)

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

c)\(325,97+86,54+103,46=515,97\)

Answer 3

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

b) 55100+3010055100+30100 = 17201720 

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