Szczegółowe wyjaśnienie:
a) czas w szkole
24h = 100%
6h = x%
-----------------------
[tex]x = \frac{6 * 100}{24} \\\\x = \frac{600}{24} \\\\x = 25%\\\\[/tex]
x = 25 %
b) sen
9h = x%
[tex]x = \frac{9 * 100}{24} \\\\x = \frac{900}{24} \\\\x = 37.5%\\\\[/tex]
x = 37.5 %
c) lekcje i jedzenie
4h = x %
[tex]x = \frac{4 * 100}{24} \\\\x = \frac{400}{24} \\\\x = 16\frac{2}{3} %\\\\[/tex]
[tex]x = 16\frac{2}{3}\\\\[/tex] %
