Question

k=12.;p=15.;a).a=16;b=24;c=30.;b).a=4;b=6;c=7.5;c).a=8;b=12c=15.Se dau proportiile:a/2=b/3;b/4=c/5.Determinati pe k si p astfel încât a/8=b/k=c/p.

Answer 1

a) 16/8 = 24/k = 30/p
2 = 24/k = 30/p
k = 24/2 = 12
p = 30/2 = 15

b) 4/8 = 6/k = 75/10/p
1/2 = 6/k = 15p/2
k = 2*6 = 12
p = 2/2*15 = 1/15

c) 8/8 = 12/k = 15/p
1 = 12/k = 15/p
k= 12
p= 15
