Question

tìm x
a)x+2 1/6=3 1/3
b)x-2 3/7=3
c)x x 1 1/3=2 2/3
 

Answer 1

a) \(x+2\frac{1}{6}=3\frac{1}{3}\)

\(x+\frac{13}{6}=\frac{10}{3}\)

\(x=\frac{10}{3}-\frac{13}{6}=\frac{7}{6}\)

b) \(x-2\frac{3}{7}=3\)

\(x-\frac{17}{7}=3\)

\(x=3+\frac{17}{7}=\frac{38}{7}\)

c) \(x.1\frac{1}{3}=2\frac{2}{3}\)(dấu chấm là dấu nhân)

\(x.\frac{4}{3}=\frac{8}{3}\)

\(x=\frac{8}{3}:\frac{4}{3}=2\)
