Answer 1

$(a)125\% \: de \: 40 = \\ \frac{125 \times 40}{100} = \frac{5000}{100} = 50$
$b)10\% \: de \: 860 \\ \frac{10 \times860}{100} = \frac{8600}{100} = 86$
$c)20\% \: de \: 860 \\ \frac{20 \times 860}{100} = \frac{17200}{100} = 172$
$d) 30\% \: de \: 860 \\ \frac{30 \times 860}{100} = \frac{25800}{100} = 258$
$e)5\% \: de \: 800 \\ \frac{5 \times 800}{100} = \frac{4000}{100} = 40$
$f)10\% \: de \: 280 \\ \frac{10 \times 280}{100} = \frac{2800}{100} = 28$
$g)5\% \: de \: 280 \\ \frac{5 \times 280}{100} = \frac{1400}{100} = 14$
$h)20\% \: de \: 280 \\ \frac{20 \times 280}{100} = \frac{5600}{100} = 56$
$i)25\% \: de \: 280 \\ \frac{25 \times 280}{100} = \frac{7000}{100} = 70$
