Закончи вычисления. 1) 38 * 4 = 30 * 4 + 8 * 4 =---------------------------- 2) 53 * 6 = 50 * --- + 3 * ----- =----------------------------------------- 3) 246 * 5 = 200 * 5 + 40 * 5 + ------------------------------------------------------------- 4) 1435 * 2 = 1000 * 2 + --------------------------------------------------------------------------- .

Answer 1

1)38*4=30*4+8*4=120+32=152
2)53*6=50*6+3*6=300+18=318
3)246*5=200*5+40*5+6*5=1000+200+30=1230
4)1435*2=1000*2+400*2+30*2+5*2=2870

Answer 2

1)120+32=152
2)50*6+3*6=300+18=318
3)200*5+40*5+6*5=1000+200+30=1230
4)1000*2+400*2+30*2+5*2=2000+800+60+10=2870
