Question

Scrie numerele formate din:
a) 4 mii si 16 sute
b) 2 mii; 13 sute si 18 zeci
c) 3 mii; 15 sute; 12 zeci si 17 unitati
d) 3 mii si 25 de sute
e) 4 mii si 37 de zeci
f) 9 mii; 15 sute si 20 de zec

Answer 1

a) 4 mii = 4 × 1000 = 4 000
16 sute = 16 × 100 = 1 600

4 mii si 16 sute = 4000 + 1600 = 5600

b) 2 mii = 2 × 1000 = 2 000
13 sute = 13 × 100 = 1 300
18 zeci = 18 × 10 = 180

2 mii; 13 sute si 18 zeci = 2000+1300+180 = 3480

c) 3 mii = 3×1000 = 3000
15 sute = 15×100 = 1 500
12 zeci = 12×10 = 120
17 unitati = 1 × 17 = 17

3 mii; 15 sute; 12 zeci si 17 unitati =
= 3000+1500+120+17 = 4 637

d) 3 mii = 3×1000 = 3000
25 sute = 25×100 = 2500

3 mii si 25 de sute = 3000+2500=5 500

e) 4 mii = 4×1000 = 4 000
37 zeci = 37×10 = 370

4 mii si 37 de zeci = 4000 + 370 = 4 370

f) 9 mii = 9×1000 = 9 000
15 sute = 15×100 = 1 500
20 zeci = 20 × 10 = 200

9 mii; 15 sute si 20 de zeci = 9000+1500+200 = 10 700
