Question

tính giá trị biểu thức 

2/3 + 3/4 : 6/7 + 1/8 x 4/3

 

Answer 1

\(\frac{2}{3}+\frac{3}{4}:\frac{6}{7}+\frac{1}{8}\cdot\frac{4}{3}\)

\(=\frac{2}{3}+\frac{3}{4}\cdot\frac{7}{6}+\frac{1}{8}\cdot\frac{4}{3}\)

\(=\frac{2}{3}+\frac{21}{24}+\frac{4}{24}\)

\(=\frac{16}{24}+\frac{21}{24}+\frac{4}{24}\)

\(=\frac{37}{24}+\frac{4}{24}\)

\(=\frac{41}{24}\)

Answer 2

2/3 + 3/4 : 6/7 + 1/8 x 4/3 = 2/3 + 7/8 + 1/6

                                      = 16/24 + 21/24 + 4/24

                                      = 41/24

Answer 3

\(\frac{2}{3}+\frac{3}{4}:\frac{6}{7}+\frac{1}{8}x\frac{4}{3}=\frac{2}{3}+\frac{3}{4}x\frac{7}{6}+\frac{1}{8}x\frac{4}{3}=\frac{2}{3}+\frac{7}{8}+\frac{1}{6}\)= \(\frac{16}{24}+\frac{21}{24}+\frac{4}{24}\)=\(\frac{41}{24}\)

Good Luck!

Answer 4

\(\frac{2}{3}\)+ \(\frac{7}{8}\)+ \(\frac{1}{6}\)= \(\frac{41}{24}\)
