Q:
If then which one of the following statements is correct?
Answer & Explanation
Answer: C) Each fraction is equal to 1/2 or -1
Explanation: a/(b+c) = b/(c+a) = c/(a+b)
Taking reciprocal and adding 1 to each ratio we get;
(b+c)/a + 1 = b/(c+a) + 1 = c/(a+b) + 1
Or (a+b+c)/a = (a+b+c)/b = (a+b+c)/c
So this can only be equal when a=b=c or a+b+c = 0
When a=b=c we get
a/(b+c)= ½When a+b+c = 0 we get
b+c = -a
So a/(b+c) = -1
So the ratios are ½ or -1
