Question

Efectueaza:
a) 250 mg + 19 cg + 7g = ? cg
b) 902 g - 3000 mg - 630 dg
= ? g
c) 730 dg - 10 g +10 dg - 3000 mg = ? g
d) 175 g +230 dg - 200 cg - 2000 mg =? g

Answer 1

a)250 mg = 25 cg
7 g = 700 cg
25 cg + 19 cg + 700 cg = 744 cg

b)3.000 mg = 3 g
630 dg = 63 g
902 g - 3 g - 63 g= 836 g

c)730 dg = 73 g
10 dg = 1 g
3.000 mg = 3 g
73 g -10 g + 1 g -3 g = 61 g

d)230 dg = 23 g
200 cg = 2 g
2000 mg = 2 g
175 g + 23 g- 2g - 2 g = 194 g
