Answer 1

x.3.6=0,17.0,9

x.18=0.119

x=0.119:18

x=\(\frac{119}{18000}\)

2,3:2,8.x=57,5

\(\frac{23}{28}\).x=57.5

x=57,5:23/28

x=70

0.16:(x:3,5)=2,8

x:3.5=0.16:2,8

x:3,5=2/35

x=2/35x3,5

x=0.2

k mình nha k b nữa...^_^...thanks♥

Answer 2

\(3,6x=0,17\cdot0,9\)

\(\Rightarrow3,6x=0,153\)

\(\Rightarrow x=0,153:3,6\)

\(\Rightarrow x=0,0425\)

Answer 3

\(2,3:2,8x=57,5\)

\(\Rightarrow2,3:57,5=2,8x\)

\(\Rightarrow2,8x=0,04\)

\(\Rightarrow x=\frac{0,04}{2,8}\)
