1) 3\frac{9}{4} = \frac{3 \cdot 4 + 9}{4} = \frac{12 + 9}{4} = \frac{21}{4};

\frac{21}{4} : \frac{1}{100} = \frac{21}{4} \cdot \frac{100}{1} = \frac{2100}{4} = 525;

5\frac{1}{20} = \frac{5 \cdot 20 + 1}{20} = \frac{100 + 1}{20} = \frac{101}{20};

\frac{101}{20} : \frac{1}{100} = \frac{101}{20} \cdot \frac{100}{1} = \frac{10100}{20} = 505;

25\frac{1}{25} = \frac{25 \cdot 25 + 1}{25} = \frac{625 + 1}{25} = \frac{626}{25};

\frac{626}{25} : \frac{1}{100} = \frac{626}{25} \cdot \frac{100}{1} = \frac{62600}{25} = 2504;

110\frac{3}{5} = \frac{110 \cdot 5 + 3}{5} = \frac{550 + 3}{5} = \frac{553}{5};

\frac{553}{5} : \frac{1}{100} = \frac{553}{5} \cdot \frac{100}{1} = \frac{55300}{5} = 11060.

525 + 505 + 2504 + 11060 = 14594;

14594 : \frac{1}{100} = 14594 \cdot 100 = 1459400;

\frac{1459400}{100} = 925.

2) 1,8 : \frac{1}{100} = 1,8 \cdot 100 = 180;

0,27 : \frac{1}{100} = 0,27 \cdot 100 = 27;

0,05 : \frac{1}{100} = 0,05 \cdot 100 = 5;

6,72 : \frac{1}{100} = 6,72 \cdot 100 = 672;

9,03 : \frac{1}{100} = 9,03 \cdot 100 = 903;

9,9 : \frac{1}{100} = 9,9 \cdot 100 = 990.
