Question

2/9 nhân x = 6/15 : 4/5 

Answer 1

rac roi qua

Answer 2

2/9 . x = 6/15 : 4/5

2/9 . x = 6/15 . 5/4

2/9 . x = 1/2

        x = 1/2 : 2/9

        x = 1/2 . 9/2

        x = 9/4

Answer 3

2/9*x=6/15:4/5

2/9*x=1/2

x=1/2:2/9

x=9/4

(* là nhân ấy)

Answer 4

\(\frac{2}{9}.x=\frac{6}{15}:\frac{4}{5}\)

\(\Leftrightarrow\)\(\frac{2}{9}.x=\frac{6}{15}.\frac{5}{4}\)

\(\Leftrightarrow\)\(\frac{2}{9}.x=\frac{1}{2}\)

\(\Leftrightarrow\)\(x=\frac{1}{2}:\frac{2}{9}=\frac{1}{2}.\frac{9}{2}\)

\(\Leftrightarrow\)\(x=\frac{9}{4}\)Vậy x= 9/4

Answer 5

x = 9/4 nha
