Explicación paso a paso:
1)
[tex]\frac{4}{10} = \frac{x}{60} \\60(\frac{4}{10} )=x\\x=60(\frac{4}{10} )\\x=(\frac{240}{10} )\\X=24[/tex]
2)
[tex]\frac{9}{12} =\frac{12}{x}\\x(\frac{9}{12}) =12\\\\x =12(\frac{12}{9})\\\\\\x= \frac{144}{9} \\\\x=16[/tex]
3)
[tex]\frac{8}{32} =\frac{2}{x} \\x(\frac{8}{32}) =2\\x =2(\frac{32}{8\\})\\x=\frac{64}{8} \\x=8[/tex]
4)
[tex]\frac{3}{x}=\frac{x}{12} \\12(\frac{3}{x})=x\\12=x(\frac{x}{3})\\12=\frac{x^{2} }{3} \\x^{2} =12(3)\\x^{2} =36\\x=\sqrt{36} \\x=+-6[/tex]
