Answer 1

Răspuns:

10 kg+75kg-12kg = 73 kg

100 g+950g+2*50g = 1150 g

100- 4*5t- 7*5t= 100-20t-35t = 45 t

Aici cred ca ai gresit cand ai scris exercitiul

(15+24)*2 dg + 70:10 dg= 39*2 dg + 7dg = 85 dg

(20*10+5*55) hg + 22hg = (200+ 275) hg + 22 hg= 475 hg+ 22 hg = 497 hg

150: 3 cg + 15*20 cg= 50cg+ 300 cg = 350 cg

(72:9+88:8)*2 mg = 19*2 mg = 38 mg

124: 4 dag+ 3*27dag= 31 dag+ 81 dag= 112 dag

7*77 v + 77:7 v +77v = 539v+11v+77v= 550v+77v

= 627 v

(114-2*3+ 6:3)*4 kg= 110*4 kg= 440 kg

Aici nu stiu ce inseamna semnul ~ imi pare rau!

Sper ca te-am ajutat!
