Question

-7 5/11 + 9 1/6; (-1 2/3) : (- 5/18); 0, 78-(-1,23) помогите пожалуйста ​

Answer 1

Пошаговое объяснение:

-7 5/11 + 9 1/6 = -7 30/66 + 9 11/66 =

-7 30/66 + 8 77/66 = 1 47/66

-1 2/3 : (-5/18) = -5/3 * (-18/5) = -1/1 * (-6/1) =

6/1 = 6

0,78 - (-1,23) = 0,78 + 1,23 = 2,01

Answer 2

$- 7 \frac{5}{11} + 9 \frac{1}{6} = - 7 \frac{30}{66} + 9 \frac{11}{66} = - 7 \frac{30}{66} + 8 \frac{77}{66} = 1 \frac{47}{66}$

$( - 1 \frac{2}{3} )\div ( - \frac{5}{18} ) = \frac{5 \times1 8}{3 \times 5} = 6$

$0.78 - ( - 1.23) = 0.78 + 1.23 = 2.01$
