Answer 1

$\frac{60}{100} x=20=\ \textgreater \ 60x=20*100=\ \textgreater \ x=2000:60=\ \textgreater \ x=33,33 \\ \frac{60}{100} x=50=\ \textgreater \ 60x=50*100=\ \textgreater \ x=5000:60=\ \textgreater \ x=83,33 \\ \frac{60}{100} x=458=\ \textgreater \ 60x=458*100=\ \textgreater \ x=45800:60=\ \textgreater \ x=763,33 \\ \frac{60}{100} x= \frac{2}{3} =\ \textgreater \ 60x=100 \frac{2}{3} =\ \textgreater \ 69x=100,66=\ \textgreater \ x=1,45 \\ \frac{60}{100} x=32=\ \textgreater \ 60x=32*100=\ \textgreater \ x=3200:60=\ \textgreater \ x=53,33 \\ \frac{60}{100}x=480=\ \textgreater \ 60x=480*100=\ \textgreater \ x=48000:60=\ \textgreater \ x=800 \\ \frac{60}{100} x=256=\ \textgreater \ 60x=256*100=\ \textgreater \ x=25600:60=\ \textgreater \ x=426,66$
