Odpowiedź:
a) 50% to połowa, czyli można to obliczyć jako
[tex]26 \div 2 = 13[/tex]
b)
[tex]20\% \times 75 = \frac{20}{100} \times \frac{75}{1} = \frac{20}{20} \times \frac{15}{1} = \frac{300}{20} = 15[/tex]
c)
[tex]5\% \times 100 = \frac{5}{100} \times \frac{100}{1} = \frac{5}{1} \times \frac{1}{1} = 5[/tex]
d)
[tex]25\% \times 48 = \frac{25}{100} \times \frac{48}{1} = \frac{25}{50} \times \frac{24}{1 } = \frac{600}{50} = 12[/tex]
e)
[tex]130\% \times 5000 = \frac{130}{100} \times \frac{5000}{1} = \frac{130}{1} \times \frac{50}{1} = 6500[/tex]
f)
[tex]40\% \times 650 = \frac{40}{100} \times \frac{650}{1} = \frac{40}{10} \times \frac{65}{1} = \frac{2600}{10} = 260[/tex]
g)
[tex]1\% \times 200 = \frac{1}{100} \times \frac{200}{1} = \frac{1}{1} \times \frac{2}{1} = 2[/tex]
h)
[tex]200\% \times 168 = \frac{200}{100} \times \frac{168}{1} = \frac{200}{50} \times \frac{84}{1} = \frac{16800}{50} = 336[/tex]
i)
[tex]35\% \times 35 = \frac{35}{100} \times \frac{35}{1} = \frac{35}{20} \times \frac{7}{1} = \frac{245}{20} = 12.25[/tex]
j)
[tex]15\% \times 200 = \frac{15}{100} \times \frac{200}{1} = \frac{15}{1} \times \frac{2}{1} = 30[/tex]
mam nadzieje że pomogłam
