Answer 1

Ответ:

1)$\frac{8}{10}$⁷+$\frac{3}{7}$¹⁰=$\frac{56}{70} +\frac{30}{70} =\frac{80}{70}$\

2)$3\frac{1}{3}$¹⁰-$2\frac{5}{10}$³=$3\frac{10}{30} - 2\frac{15}{30}$=$2\frac{40}{30} -2\frac{15}{30} =\frac{25}{30} =\frac{5}{6}$

3)$4\frac{9}{10}$⁹+$1\frac{1}{9}$¹⁰=$4\frac{81}{90} +1\frac{10}{90} = 5\frac{91}{90} =\frac{541}{90} =6\frac{1}{90}$

4)$26\frac{1}{11}$¹⁰-$5\frac{7}{10}$¹¹=$26\frac{10}{110}-5\frac{77}{110} = 25\frac{120}{110} -5\frac{77}{110}=20\frac{43}{110}$

5)$40\frac{8}{10}$³$15\frac{2}{3}$¹⁰=$40\frac{24}{30} + 15\frac{20}{30} = 55\frac{44}{30} =56\frac{14}{30}$

6)$18\frac{5}{13}$¹⁰-$9\frac{5}{10}$¹³=$18\frac{50}{130} - 9\frac{65}{130} =17\frac{180}{130} -9\frac{65}{130} =8\frac{115}{130}$
