b)50x100:1000=5%
c)20x100:400=5%
d)50x100:500=10%

Answer 2

$a)~\frac{p}{100}*120=36$
$\frac{36*100}{120}=\frac{3600}{120}=$30%

$b)~\frac{p}{100}*1000=50$
$\frac{50*100}{1000}=\frac{5000}{1000}=$5%

$c)~\frac{p}{100}*400=20$
$\frac{20*100}{400}=\frac{2000}{400}=$5%

$d)~\frac{p}{100}*500=50$
$\frac{50*100}{500}=$10%
