Percent

From 99 children who participated in the ski course were 23 excellent skiers, 13 good and 20 average and the rest were beginners.

Calculate this data in percentages.

Correct result:

p1 =  23.2 %
p2 =  13.1 %
p3 =  20.2 %
p4 =  43.4 %

Solution:

$p_1 = \dfrac{ 23}{ 99} \cdot 100 = 23.2 \%$
$p_2 = \dfrac{ 13}{ 99} \cdot 100 = 13.1 \%$
$p_3 = \dfrac{ 20}{ 99} \cdot 100 = 20.2 \%$
$p_4 = \dfrac{ 99-23-13-20}{ 99} \cdot 100 = 43.4 \%$
