[tex]\frac{x}{100} =\frac{6120}{180}[/tex]
[tex]=> 180x = 6120 * 100[/tex]
[tex]180 x = 612000[/tex]
[tex]x=\frac{612000}{180}[/tex]
[tex]x=3 400[/tex]
[tex]\it \dfrac{x}{100}\cdot 6120=180\ \Rightarrow\ x\cdot\dfrac{6120}{100}=180\ \Rightarrow\ x=180\cdot\dfrac{100}{6120}=\dfrac{1800^{(18}}{612}=\\ \\ =\dfrac{100}{34}\approx2,9[/tex]
