39+63.36+61+36.64= 9.88-(10.55-2.777)= 49.83-(62.51+3.49)= 31.89-(11.89+8.004)= 54.03-(7.27+27.03)= 39.19-(15.796+4.204)=

Решим данные примеры.

39 + 63.36 + 61 + 36.64 = 200.

9.88 - (10.55 - 2.777) = 9.88 - 7.773 = 2.107.

49.83 - (62.51 + 3.49) = 49.83 - 66 = 16.17.

31.89 - (11.89 + 8.004) = 31.89 - 19.894 = 11.996.

54.03 - (7.27 + 27.03) = 54.03 - 34.3 = 19.73.

39.19 - (15.796 + 4.204) = 39.19 - 20 = 19.19.

0.36 * (- 5.95) = - 2.142.

- 0.5454 : 0.018 = - 30.3.
