Question

Tìm x :  1 5/7 x X =2 3/6                                 29/7 - X = 3/2+1

Answer 1

\(\frac{15}{7}\). X =\(\frac{23}{6}\)

X              = \(\frac{23}{6}\): \(\frac{15}{7}\)

x              =  \(\frac{161}{90}\)

Answer 2

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...

Answer 3

\(\frac{15}{7}.x=\frac{23}{6}\)

\(x=\frac{23}{6}:\frac{15}{7}\)

bấm máy tính sẽ ra \(x=\frac{161}{90}\)
