Question

tim x biet 3/4*x :1/2=4/5

 

 

Answer 1

x= 8/15

Answer 2

\(\frac{3}{4}\times x:\frac{1}{2}=\frac{4}{5}\)

\(x:\frac{1}{2}=\frac{4}{5}:\frac{3}{4}\)

\(x:\frac{1}{2}=\frac{16}{15}\)

\(x=\frac{16}{15}\times\frac{1}{2}=\frac{8}{15}\)

Answer 3

Bài làm

\(\frac{3}{4}xX:\frac{1}{2}=\frac{4}{5}\)

\(\frac{3}{4}xX=\frac{4}{5}x\frac{1}{2}\)

\(\frac{3}{4}xX=\frac{2}{5}\)

       \(X=\frac{2}{5}:\frac{3}{4}\)

       \(X=\frac{2}{5}x\frac{4}{3}\)

       \(X=\frac{8}{15}\)

Vậy \(X=\frac{8}{15}\)

Answer 4

3/4*x:1/2=4/5

3/4*x=4/5.1/2

3/4*x=2/5

      x=2/5:3/5

      x=2/5.5/3

      x=2/3

vậy x=2/3

chúc bạn học tốt
