Question

[Dương Nguyễn]

Tính giá trị biểu thức:

H=11/10+17/20+7/10+9/20+1/10+3/20

Answer 1

[☆Châuuu~~~(๑╹ω╹๑ )☆]

\(=\left(\dfrac{11}{10}+\dfrac{7}{10}+\dfrac{1}{10}\right)+\left(\dfrac{17}{20}+\dfrac{9}{20}+\dfrac{3}{20}\right)\\ =\dfrac{19}{10}+\dfrac{29}{20}=\dfrac{19\times2}{10\times2}+\dfrac{29}{20}=\dfrac{38}{20}+\dfrac{29}{20}\\ =\dfrac{47}{20}\)

Answer 2

[Thái Hưng Mai Thanh]

\(H=\left(\dfrac{11}{10}+\dfrac{7}{10}+\dfrac{1}{10}\right)+\left(\dfrac{17}{20}+\dfrac{9}{20}+\dfrac{3}{20}\right)\)

\(H=\dfrac{19}{10}+\dfrac{29}{20}\)

\(H=\dfrac{67}{20}\)
