6.вычисли. дроби 4+3 3/9; 19 8/10-3; 19 3/7-17; 14 1/9+6 4/9; 14 1/8+14; 8 5/6-4 3/6

Answer 1

4+3 3/9=4+3+3/9=7 3/9= 7 1/3;

19 8/10-3=19-3+8/10=16 8/10=16 4/5;

19 3/7-17=19-17+3/7=2 3/7;

14 1/9+6 4/9=(14+6)+(1/9+4/9)=20 5/9;

14 1/8+14=14+14+1/8=28 1/8;

8 5/6-4 3/6=(8-4)+(5/6-3/6)=4 2/6=4 1/3.

Answer 2

Ответ:

Пошаговое объяснение:

$4+3frac{3}{9} =frac{36}{9} +frac{30}{9} =frac{66}{9} =frac{22}{3} =7frac{1}{3}$

$19frac{8}{10} -3=frac{198}{10} -frac{30}{10} =frac{168}{10} =frac{84}{5} =16frac{4}{5}$

$19frac{3}{7} -17=frac{136}{7} -frac{119}{7} =frac{17}{7} =2frac{3}{7}$

$14frac{1}{9} +6frac{4}{9} =frac{127}{9} +frac{58}{9} =frac{185}{9} =20frac{5}{9}$

$14frac{1}{8} +14=frac{113}{8} +frac{112}{8} =frac{225}{8} =28frac{1}{8}$

$8frac{5}{6} -4frac{3}{6} =frac{53}{6} -frac{27}{6} =frac{26}{6} =4frac{2}{6}$
