Question

daca a:b=3 b:2=c iar a+b+c=99 afla a b c va rog urgent

Answer 1

Răspuns

a=66, b= 22, c=11

Explicație pas cu pas:

a+b+c=99

a:b=3 => a=3b

b:2=c= b=2c

Daca a= 3b (3 ori b)=> a= 2c ori 3

=> a= 6c

Inlocuim in prima relatie:

6c+2c+c=99

9c=99/:9

c=11

b= 2 ori 11

b=22

a= 22 ori 3

a= 66

Verificare:

66+22+11=99

66: 22=3

22:2= 11

Answer 2

a+b+c=99
a:b=3 --->a=3b

b:2=c---->b=2c
a=3×b =>a=2c×3=>a=6c
6c+2c+c=99
9c=99
c=99:9
c=11
b=2×c=>b=2×11=>b=22
a=3×b=>a=3×22=>a=66

VERIFICARE: 66+22+11=
88+11=99

66:22=3

22:2=11
