Question

(10 3/7 + 3 5/16) - 5 3/7

Answer 1

Ответ:

(10 3/7+3 5/16)-5 3/7

((10+3)+(3/7+5/16))-5 3/7

5 3/7=5*7+3=38/7

((10+3)+(3/7+5/16))-38/7

(13+(3/7+5/16))-38/7

3/7+5/16

48+35//112

83/112

(13+83/112)-38/7

13 83/112-38/7

13 83/112=13*112+83=1539/112

1539/112-38/7

1539-608//112

931/112

Сокращаем на общий делитель 7:

133/16

Answer 2

Ответ:

$(10 \frac{3}{7 }+ 3 \frac{5}{16} )- 5 \frac{3}{7} =( 10 \frac{48}{112} +\\ 3 \frac{35}{112} )- 5 \frac{48}{112} = 13 \frac{83}{112} - 5 \frac{48}{112} = 8 \frac{35}{112}$
