SI : A/a = B/b = C/c = D/d = K ;
A+B+C+D =45
a+b+c+d=125 :
HALLAR: raiz de K
este simbolo ( / ) SIGNIFICA " SOBRE"
HACEMOS PROPORCION:
A/a = B/b = C/c = D/d = K
A=ak; B=bk; C=ck y D=dk
A+B+C+D=ak+bk+ck+dk=45
ak+bk+ck+dk=45 factorizamos "k"
k(a+b+c+d)=45 pero a+b+c+d=125
k(125)=45
k=9/25 entonces raiz de "k"=3/5
