Question

3 целых 2/8-(-3 целых 1/7)
-4,7-(4 целых 2/7)
-4,7+6 целых 1/3
Помогите пожалуйста.

Answer 1

Ответ:

3 2/8 + 3 1/7 = 3 14/56 + 3 8/56 = 6 22/56 = 6 11/28

-4,7 - 4 2/7 = -4 49/70 - 4 20/70 = -8 69/70

-4,7 + 6 1/3 = -4 21/30 + 6 10/30 = 5 40/30 - 4 21/30 = 1 19/30

Answer 2

$3\frac{2}{8}-(-3\frac{1}{7})=3\frac{14}{56} +3\frac{8}{56} =6\frac{22}{56} =6\frac{11}{28}$

$-4.7-(4\frac{2}{7} )=-4\frac{7}{10} -4\frac{2}{7}=-4\frac{49}{70} -4\frac{20}{70} =-8\frac{69}{70}$

$-4.7+6\frac{1}{3} =-4\frac{21}{30}+6\frac{10}{30}=6\frac{10}{30}-4\frac{21}{30}=1\frac{19}{30}$
