Выражение: 0.25+1/12:(1/3*1.25-9/16)
Ответ: -(9//28)
Решаем по действиям:
1. 1/12=(1//12)
2. 1.25/3=(5//12)
3. 9/16=(9//16)
4. (5//12)-(9//16)=-(7//48)
5. (1//12):(-(7//48))=-(1//12)/(7//48)
6. (1//12)/(7//48)=(4//7)
7. 0.25+(-(4//7))=0.25-(4//7)
8. 0.25-(4//7)=-(9//28)
Решаем по шагам:
1. 0.25+(1//12):(1.25/3-9/16)
1.1. 1/12=(1//12)
2. 0.25+(1//12):((5//12)-9/16)
2.1. 1.25/3=(5//12)
3. 0.25+(1//12):((5//12)-(9//16))
3.1. 9/16=(9//16)
4. 0.25+(1//12):(-(7//48))
4.1. (5//12)-(9//16)=-(7//48)
5. 0.25+(-(1//12)/(7//48))
5.1. (1//12):(-(7//48))=-(1//12)/(7//48)
6. 0.25+(-(4//7))
6.1. (1//12)/(7//48)=(4//7)
7. 0.25-(4//7)
7.1. 0.25+(-(4//7))=0.25-(4//7)
8. -(9//28)
8.1. 0.25-(4//7)=-(9//28)
