Calculează, apoi efectuează proba prin înmulţire şi împărțire: b) 59 000: 1 000 = c) 3 000:1 000 = 66 000: 1 000 = 5 005 : 1 000 = a) 800:8= 500 : 5 = d) 1 650:10 = 7 200:10 = VA ROG FACETI DAU STEA INIMA COROANA SI FOLLOW VA ROOG​

Answer 1

Răspuns:

a) 59000 : 1000 = 59

proba: 1000 × 59 = 59000

59000 : 59 = 1000

b) 3000 : 1000 = 3

proba: 1000 × 3 = 3000

3000 : 3 = 1000

c) 66000 : 1000 = 66

proba: 1000 × 66 = 66000

66000 : 66 = 1000

d) 5000 : 1000 = 5

proba: 1000 × 5 = 5000

5000 : 5 = 1000

e) 800 : 8 = 100

proba: 8 × 100 = 800

800 : 100 = 8

f) 1650 : 10 = 165

proba: 10 × 165 = 1650

1650 : 165 = 10

g) 200 : 10 = 20

proba : 10 × 20 = 200

200 : 20 = 10

Answer 2

B. 59000:1000=59
59•1000=59000
59000:59=1000
C. 3000:1000=3
1000•3=3000
3000:3=1000
66000:1000=66
66•1000=66000
66000:66=1000
800:8=100/800:100=8/8•100=800
500:5=100/500:100=5/5•100=500
1650:10=165/1650:165=10/165•10=1650
7200:10=720/7200:720=10/720•10=7200
