Question

a, b, and c represent three different numbers. each is chosen from the set 3 5 7 9 . what is the least possible value of a/b+c?

Answer 1

the larger the denominator compared to the numerator, the smaller the number, so:

`(b+c)\gg a\Rightarrow(a)/(b+c)\to0`

So, let's choose the smallest number as a numerator, and the biggest numbers as a denominator:

`(3)/(7+9)=(3)/(16)=0.1875`
