Найдите числа, обратные числам:
а) $\frac{10}{27}; \frac{12}{59}; \frac{23}{98}; \frac{11}{122}; \frac{43}{315}; \frac{10}{3}; \frac{41}{8}$;
б) $11\frac{11}{12}; \frac{1}{20}; 80; 100; 1; 0,5; 1,2$.
$1 : \frac{10}{27} = 1 * \frac{27}{10} = 2\frac{2}{10}$;
$1 : \frac{12}{59} = 1 * \frac{59}{12} = 4\frac{11}{12}$;
$1 : \frac{23}{98} = 1 * \frac{98}{23} = 4\frac{1}{23}$;
$1 : \frac{11}{122} = 1 * \frac{122}{11} = 1\frac{1}{11}$;
$1 : \frac{43}{315} = 1 * \frac{315}{43} = 7\frac{14}{43}$;
$1 : \frac{10}{3} = 1 * \frac{3}{10} = \frac{3}{10}$;
$1 : \frac{41}{8} = 1 * \frac{8}{41} = \frac{8}{41}$.
$1 : 11\frac{11}{12} = 1 : \frac{143}{12} = 1 * \frac{12}{143} = \frac{12}{143}$;
$1 : \frac{1}{20} = 1 * \frac{20}{1} = 20$;
$1 : 80 = 1 * \frac{1}{80} = \frac{1}{80}$;
$1 : 100 = 1 * \frac{1}{100} = 0,1$;
$1 : 1 = 1 * 1 = 1$;
$1 : 0,5 = 1 : \frac{5}{10} = 1 : \frac{1}{2} = 1 * 2 = 2$;
$1 : 1,2 = 1 : 1\frac{2}{10} = 1 : \frac{12}{10} = 1 * \frac{10}{12} = \frac{5}{6}$.
