Чтобы найти число, делим известное значение на соответствующую часть.
- \(7\frac{1}{5}:0{,}12=\frac{36}{5}\cdot\frac{25}{3}=60\).
- \(2\frac{5}{8}:0{,}03=\frac{21}{8}\cdot\frac{100}{3}=87{,}5\).
- \(3\frac{1}{3}:0{,}08=\frac{10}{3}\cdot\frac{25}{2}=\frac{125}{3}=41\frac{2}{3}\).
- \(5\frac{11}{15}:0{,}43=\frac{86}{15}\cdot\frac{100}{43}=\frac{40}{3}=13\frac{1}{3}\).
- \(9\frac{4}{5}:0{,}21=\frac{49}{5}\cdot\frac{100}{21}=\frac{140}{3}=46\frac{2}{3}\).
- \(3\frac{3}{16}:0{,}68=\frac{51}{16}\cdot\frac{25}{17}=\frac{75}{16}=4\frac{11}{16}\).
- \(2\frac{3}{50}:0{,}006=\frac{103}{50}\cdot\frac{500}{3}=\frac{1030}{3}=343\frac{1}{3}\).
- \(3\frac{3}{20}:0{,}021=\frac{63}{20}\cdot\frac{1000}{21}=150\).
- \(7\frac{7}{8}:0{,}441=\frac{63}{8}\cdot\frac{1000}{441}=\frac{125}{7}=17\frac{6}{7}\).
- \(7\frac{1}{9}:0{,}512=\frac{64}{9}\cdot\frac{125}{64}=\frac{125}{9}=13\frac{8}{9}\).
- \(5\frac{1}{16}:0{,}027=\frac{81}{16}\cdot\frac{1000}{27}=\frac{1875}{8}=234\frac{3}{8}\).
- \(12:0{,}303=12\cdot\frac{1000}{303}=\frac{4000}{101}=39\frac{61}{101}\).
Ответ: 1) 60; 2) 87,5; 3) 41 2/3; 4) 13 1/3; 5) 46 2/3; 6) 4 11/16; 7) 343 1/3; 8) 150; 9) 17 6/7; 10) 13 8/9; 11) 234 3/8; 12) 39 61/101.
