С решением пожалуйста ​

Answer 1

13 7/12 + 42 1/6 = 13 7/12 + 42 2/12 = 55 9/12 = 55 3/4

$872 \frac{5}{8} + 15 \frac{25}{36} = 872 \frac{45}{72} + 15 \frac{50}{72} = 887 \frac{95}{72} = 888 \frac{23}{72}$

$473 \frac{5}{12} - 362 \frac{4}{21} = 473 \frac{35}{84} - 362 \frac{16}{84} = 111 \frac{19}{84}$

$55 - 23 \frac{51}{64} = 54 \frac{64}{64} - 23 \frac{51}{64} = 31 \frac{13}{64}$

$11 \times 4 \frac{17}{31} = \frac{11 \times 141}{31} = \frac{1551}{31} = 50 \frac{1}{31}$

$52 \frac{2}{3} \div 13 = \frac{158}{3 \times 13} = \frac{158}{39} = 4 \frac{2}{39}$

Пошаговое объяснение:

$13\frac{7}{12} +42\frac{1}{6} =\frac{163}{12} +\frac{253}{6} =\frac{163}{12} +\frac{506}{12} =\frac{669}{12} =\frac{223}{4} =55\frac{3}{4} =55.75$

$872\frac{5}{8} +15\frac{25}{36} =\frac{6981}{8} +\frac{565}{36} =\frac{62829}{72} +\frac{1130}{72} =\frac{63959}{72} =888\frac{23}{72}$

$473\frac{5}{12} -362\frac{4}{21} =\frac{5681}{12} -\frac{7606}{21} =\frac{39767}{84} -\frac{30424}{84} =\frac{9343}{84} =111\frac{19}{84}$

$55-23\frac{51}{64} =\frac{3520}{64} -\frac{1523}{64} =\frac{1997}{64} =31\frac{13}{64}$

$11*4\frac{17}{31} =\frac{11}{1} *\frac{141}{31} =\frac{1551}{31} =50\frac{1}{31}$

$52\frac{2}{3} :13=\frac{158}{3} :\frac{13}{1} =\frac{158}{3} *\frac{1}{13} =\frac{158}{39} =4\frac{2}{39}$
