\(\frac{15}{7}\). X =\(\frac{23}{6}\)
X = \(\frac{23}{6}\): \(\frac{15}{7}\)
x = \(\frac{161}{90}\)
a,/ Đề bài là thek này :> ? / : \(1\frac{5}{7}\cdot x=2\frac{3}{6}\)
\(\frac{12}{7}\cdot x=\frac{5}{2}\)
\(x=\frac{5}{2}:\frac{12}{7}\)
\(x=\frac{35}{24}\)
Vậy...
b, \(\frac{29}{7}-x=\frac{3}{2}+1\)
\(\frac{29}{7}-x=\frac{5}{2}\)
\(x=\frac{23}{14}\)
Vậy...
\(\frac{15}{7}.x=\frac{23}{6}\)
\(x=\frac{23}{6}:\frac{15}{7}\)
bấm máy tính sẽ ra \(x=\frac{161}{90}\)
