Question

-2,4(2,5a-1,5b)+0,5(1,8b+5,6a) 4/9(1 1/2c-3/8)-(1 1/6-1 1/3c) (1/6a+6,5)-(2 7/9a+3 1/3) 6(1/4k-5/6)-15(0,6-2 1/3k) Прошу.

Answer 1

1) 2,4(2,5a-1,5b)+0,5(1,8b+5,6a)=6а-3.6b+0.9b+2.8a=8.8a-2.7b

4/9(1 1/2c-3/8)-(1 1/6-1 1/3c)=ответ на фото

2с-1 целая 1/3

(1/6a+6,5)-(2 7/9a+3 1/3)= ответ на фото

-2 целых 11/18а+3 ц 1/6

6(1/4k-5/6)-15(0,6-2 1/3k)= ответ на фото

36.5 к- 14
