6/5 - x = 7/8
x = 6/5 - 7/8
x = 13/40
Chúc bạn học tốt!! ^^
\(\dfrac{6}{5}-x=\dfrac{7}{8}\\ \Rightarrow x=\dfrac{6}{5}-\dfrac{7}{8}\\ \Rightarrow x=\dfrac{13}{40}\)
6/5 - x = 7/8
x = 6/5 - 7/8
x = 13/40
\(\dfrac{6}{5}-x=\dfrac{7}{8}\)
\(x=\dfrac{6}{5}-\dfrac{7}{8}\)
\(x=\dfrac{48}{40}-\dfrac{35}{40}\)
\(x=\dfrac{13}{40}\)
6/5 - x =7/8
x = 6/5 - 7/8
x = 13/40
chúc bn học tốt !!!
