Question

Tính giá trị biểu thức:

G = 9/8+23/24+1/8+17/24+13/8+19/24
 

Answer 1

\(G=\dfrac{9}{8}+\dfrac{23}{24}+\dfrac{1}{8}+\dfrac{17}{24}+\dfrac{13}{8}+\dfrac{19}{24}\\ \Rightarrow G=\left(\dfrac{9}{8}+\dfrac{1}{8}+\dfrac{13}{8}\right)+\left(\dfrac{23}{24}+\dfrac{17}{24}+\dfrac{19}{24}\right)\\ \Rightarrow G=\dfrac{23}{8}+\dfrac{59}{24}\\ \Rightarrow G=\dfrac{69}{24}+\dfrac{59}{24}\\ \Rightarrow G=\dfrac{128}{24}\\ \Rightarrow G=\dfrac{16}{3}\)

Answer 2

\(=\left(\dfrac{9}{8}+\dfrac{1}{8}+\dfrac{13}{8}\right)+\left(\dfrac{23}{24}+\dfrac{17}{24}+\dfrac{19}{24}\right)\)

\(=\dfrac{23}{8}+\dfrac{59}{24}\)

\(=\dfrac{16}{3}\)
