Question

Решите:

(15 5/7:11+23 3/4*8/19):((4 1/2-1 5/6):7)

------------------------------------------------------

40032-(87312*0+263886:854)*108

Answer 1

(15 5/7:11+23 3/4*8/19):((4 1/2-1 5/6):7)=30

(1,3/7+10):(2,2/3:7)=30

11,3/7:8/21=30

 40032-(87312*0+263886:854)*108=4290084

1) 87312*0=0

2) 263886:854=309

3) 0+309=309

4) 40032-309=397235) 39723*108=4290084
