Question

9/13 - 7/8.x= -1/2, x là bao nhiêu ?

 

Answer 1

\(\frac{7}{8}.x=\frac{9}{13}-\frac{-1}{2}\)

\(\frac{7}{8}.x=\frac{31}{26}\)

\(x=\frac{31}{26}:\frac{7}{8}\)

\(x=\frac{124}{91}=1\frac{33}{91}\)

Answer 2

\(\frac{7}{8}.x=\frac{9}{13}-\frac{-1}{2}\)

\(\frac{7}{8}.x=\frac{31}{26}\)

\(x=\frac{31}{26}:\frac{7}{8}\)

\(x=\frac{124}{91}=1\frac{33}{91}\)
