Answer 1

а) 9% - х

100% - 18

$x = \frac{9 \times 18}{100} = \frac{9 \times 9}{50} = \frac{81}{50} = 1.62$

б) 8% - 24

100% - х

$x = \frac{100 \times 24}{8} = \frac{100 \times 3}{1} = 300$

в) 20% - х

100% - 144

$x = \frac{20 \times 144}{100} = \frac{1 \times 144}{5} = 28.8$

г) 12% - 36

100% - х

$x = \frac{100 \times 36}{12} = \frac{100 \times 3}{1} = 300$

д) 120% - х

100% - 40

$x = \frac{120 \times 40}{100} = \frac{6 \times40 }{5} = 48$

е) 5% - 30

100% - х

$x = \frac{100 \times 30}{5} = \frac{100 \times 6}{1} = 600$
