tim x:

1)x-10/3=7/15*3/5

2)8/23.46/24*x=1/3

3)x+3/22=27/121*11/9

4)1-x=49/65*5/7

Answer 1

[Trịnh Phương Vy]

\(\frac{2}{3}.x=\frac{1}{3}\)1) x-\(\frac{10}{3}\)=\(\frac{7}{15}.\frac{3}{5}\)

x-10/3=7/25

x=7/25+10/3

x=\(\frac{271}{75}\)

2)\(\frac{8}{23}.\frac{46}{24}.x=\frac{1}{3}\)

2/3.x=1/3

x=1/3:2/3

x=1/2
