dau coroana! ​

Answer 1

Răspuns:

Explicație pas cu pas:

352:c=12 rest 4

352=12c+4

12c=352-4

12c=348

c=348/12=29

20:dx35=700

20:d=700/35

20:d=20

d=1

b:8=124 rest 3

b=124*8+3=995

(4b+3):47=19 rest 6

4b+3=19*47+ 6

4b=899-3

4b=896

b=896/4=224

967:(5a+1)=10 rest 7

967=(5a+1)*10+7

967=50a+10+7

967-17=50a

50a=950

a=950/50=19

6439:8=804 rest 7
