Szczegółowe wyjaśnienie:
17% x = 16
0,17 x = 16
x = 16 / 0,17 = 1600 / 17 = [tex]94\frac{2}{17}[/tex]
35% x = 64
0,35x = 64
x = 64 /0,35 = 6400 / 35 = [tex]182\frac{30}{35}=182\frac{6}{7}[/tex]
95% x = 140
0,95 x = 140
x = 140 / 0,95 = 14000 / 95 = [tex]147\frac{35}{95}=147\frac{7}{19}[/tex]
33% x = 140
0,33 x = 140 = 14000 / 33 = [tex]424\frac{8}{33}[/tex]
140% x = 200
1,40 x = 200
x = 200 / 1,4 = 2000 / 14 = [tex]142\frac{12}{14}=142\frac{6}{7}[/tex]
[tex]17\% \ wynosi \ 16, \ \ to \ \ 16:17\% = 16:\frac{17}{100} = 16\cdot\frac{100}{17} =\frac{16000}{17} = \underline{94\frac{2}{7}}[/tex]
[tex]35\% \ wynosi \ 64, \ \ to \ \ 64:35\% =64:\frac{35}{100} = 64\cdot\frac{100}{35} =\frac{6400}{35} = 182\frac{30}{35} = \underline{182\frac{6}{7}}[/tex]
[tex]95\% \ wynosi \ 140 \ \ to \ \ 140:95\% = 140:\frac{95}{100} =140:\frac{19}{20} = 140\cdot\frac{20}{19} = \frac{2800}{19} = \underline{147\frac{7}{19}}[/tex]
[tex]33\% \ wynosi \ 140 \ \ to \ \ 140:33\% = 140:\frac{33}{100} = 140\cdot\frac{100}{33} = \frac{14000}{33} =\underline{ 424\frac{8}{33}}[/tex]
[tex]140\% \ wynosi \ 200 \ \ to \ \ 200:140\% = 200:\frac{140}{100} =200:\frac{7}{5} = 200\cdot\frac{5}{7} = \frac{1000}{7} = \underline{142\frac{6}{7}}[/tex]
Aby obliczyć liczbę z danego jej procentu, należy podzielić tę liczbę przez ten procent.
