ответ: -2,6373476

Answer 2

Выражение: (23.079/7.8-6.8/17*3.04-2.04)*3.04-2.04*0.85

ответ: -(428569//162500)

1) 23.079=23079//1000
2) 7.8=78//10
3) 78//10=39//5
4) (23079//1000)/(39//5)=(7693//2600)
5) 6.8=68//10
6) 68//10=34//5
7) (34//5)/17=(2//5)
8) 3.04=304//100
9) 304//100=76//25
10) (2//5)*(76//25)=(152//125)
11) (7693//2600)-(152//125)=(22657//13000)
12) 2.04=204//100
13) 204//100=51//25
14) (22657//13000)-(51//25)=-(3863//13000)
15) (-(3863//13000))*3.04=-(3863//13000)*3.04
16) 3.04=304//100
17) 304//100=76//25
18) (3863//13000)*(76//25)=(73397//81250)
19) 2.04=204//100
20) 204//100=51//25
21) 0.85=85//100
22) 85//100=17//20
23) (51//25)*(17//20)=(867//500)
24) -(73397//81250)-(867//500)=-(428569//162500)

Окончательный ответ: -2.63734769230769
