Answer 1

1) 40*50*25*2*9=900*50*9=405000
2)25*4*125*8=100*1000=100000
3)16*5*5*4=80*20=1600
4)250:5*12:3*4=50*4*4=800
5)86+14+22-11=100+11=111

Answer 2

(50x2)x(40x25)x9=100x1000x9=900000
(25x4)x(125x8)=100x1000=100000
(16x5x5)x4=80x5x4=400x4=1600
(250/5)x(12/3)x4=50x4x4=200x4=800
(86+14)+(22-11)=100+11=111
