Question

Se stie ca a:b=97 r 21 si a-b= 5397 Afla :(4a-b:14):8

Answer 1

daca a:b=97rest 21 , atunci a=97xb + 21
daca a-b = 5397, atunci a=5397+b
97xb+21=5397+b
97xb-b=5397-21
96xb=5376
b=5376:96
b=56
a=5397+b, a=5397+56, a=5453
Proba: 5453:56=97 rest 21

(4a-b:14):8 = (4x5453-56:14):8 = (21812-4):8=21808:8=2726
