Question

Afla catul numerilor ,, a" si ,,b"daca a=(765-758)×(89 -81)+60:2si b=46:2×4-90

Answer 1

a = (765-758) x (89 - 81) +60:2 = 7 x 8 +30 = 56 + 30 = 86
b = 46:2 x 4 - 90 = 23 x 4 = 90 = 92 - 90 = 2
a : b = 86 : 2 = 43

Answer 2

a = (765-758) x (89 - 81) +60:2 
a= 7 x 8 +30 
a= 56 + 30
a = 86
b = 46:2 x 4 - 90
b= 23 x 4 - 90
b= 92 - 90
b= 2
a : b = 86 : 2 = 43
