а) 9% - х

100% - 18

[tex]x = \frac{9 \times 18}{100} = \frac{9 \times 9}{50} = \frac{81}{50} = 1.62[/tex]

б) 8% - 24

100% - х

[tex]x = \frac{100 \times 24}{8} = \frac{100 \times 3}{1} = 300[/tex]

в) 20% - х

100% - 144

[tex]x = \frac{20 \times 144}{100} = \frac{1 \times 144}{5} = 28.8[/tex]

г) 12% - 36

100% - х

[tex]x = \frac{100 \times 36}{12} = \frac{100 \times 3}{1} = 300[/tex]

д) 120% - х

100% - 40

[tex]x = \frac{120 \times 40}{100} = \frac{6 \times40 }{5} = 48[/tex]

е) 5% - 30

100% - х

[tex]x = \frac{100 \times 30}{5} = \frac{100 \times 6}{1} = 600[/tex]
