Question

Efectuați în două moduri :
a. (600+90+6):3
b.(200+60+8):4
c.(1000+300+40+5):5
d.(1400+700+21):7
c.(72000+3600+180+27):9

Answer 1

a) (600+90+6):3=231
 (600:3)+(90:3)+(3:3)=200+30+1=231
693:3=231
b) (200+60+8):4=66
(200:4)+(60:4)+(4:4)=50+15+1=66
264:4=66
c)(1000+300+40+5):5=269
(1000:5)+(300:5)+(40:5)+(5:5)=200+60+8+1=269
1345:5=269
d)(1400+700+21):7=301
(1400:7)+(700:7)+(7:7)=200+100+1=301
2107:7=301
e)(72000+3600+180+27):9=8493
(72000:9)+(3600:9)+(180:9)+(27:9)=8000+400+20+3=8423
75807:9=8421
