Question

помогите решить пожалуйста.​

Answer 1

1).

(4  5/6-2  1/6)+(5  1/9-2  7/9)=(29/6-13/6)+(46/9-25/9)=8/3+7/3=5

2).

(13/6+2/3):17/5*(43/8-9/4)+3/2=17/6*5/17*25/8*3/2=1/6*5*25/8+3/2=125/48+3/2=197/48

Answer 2

Ответ:

1. (4 5/6 - 2 1/6) + (5 1/9 - 2 7/9) = 2 4/6 + 1 3/9 = 16/6 + 12/9 = 48/18 + 24/18 = 72/18 = 4

2. (2 1/6 + 2/3) : (4 - 3/5)(5 3/8 - 2 1/4) + 1 1/2 = (13/6 + 4/6) : 3 2/5(43/8 - 18/8) + 3/2 = (17/6 × 5/17) × 25/8 + 3/2 = 5/6 × 25/8 + 3/2 = 125/48 + 3/2 = 197/48 = 4 5/48
