Question

Вычислите удобным способом:4*17*25,5*643*2,8*475*125,73*5*4,2*916*50,5*9*200.

Answer 1

4*17*25 = 4*25*17 = 100*17 = 1700

5*643*2 = 5*2*643 = 10*643 = 6430

8*475*125 = 8*125*475 = 1000*475 = 475000

73*5*4 = 73*20 = 1460

2*916*50 = 2*50*916 = 100*916 = 91600

5*9*200 = 5*200*9 = 1000*9 = 9000
