Answer 1

38*4=30*4+8*4=120+32=152
53*6=50*6+3*6=300+18=318
246*5=200*5+40*5+6*5=1000+200+30=1230
1435*2=1000*2+400*2+30*2+5*2=2000+800+60+10=2870

Answer 2

38*4=152 30*4+8*4=120+32=152

53*6=318 50*?+3?=318 ? = (318-3)/50 ? = 6.3

246*5=1230 200*5+40*5=1000+200=1230

1435*2=2870 1000*2+?=2870 ? = 2870-2000 ? = 870
