Question

Tính giá trị biểu thức:

G =7/8+11/24+5/8+23/24+11/8+13/24

Answer 1

\(G=\dfrac{7}{8}+\dfrac{11}{24}+\dfrac{5}{8}+\dfrac{23}{24}+\dfrac{11}{8}+\dfrac{13}{24}\\ \Rightarrow G=\left(\dfrac{7}{8}+\dfrac{5}{8}+\dfrac{11}{8}\right)+\left(\dfrac{11}{24}+\dfrac{23}{24}+\dfrac{13}{24}\right)\\ \Rightarrow G=\dfrac{23}{8}+\dfrac{47}{24}\\ \Rightarrow G=\dfrac{69}{24}+\dfrac{47}{24}\\ \Rightarrow G=\dfrac{116}{24}\\ \Rightarrow G=\dfrac{29}{6}\)

Answer 2

\(=\left(\dfrac{7}{8}+\dfrac{5}{8}+\dfrac{11}{8}\right)+\left(\dfrac{11}{24}+\dfrac{24}{24}+\dfrac{13}{24}\right)\)

\(=\dfrac{23}{8}+\dfrac{58}{24}=\dfrac{127}{24}\)
