According to a+b=17, (1/5)<((a)/(b))<(1/4), then ((a)/(b))=what. (a≠0, b≠0).
根据a+b=17，(1/5)＜((a)/(b))＜(1/4)，则((a)/(b))=多少．(a≠0，b≠0)．
<gadget id="calculator">17 - 3</gadget>
<output>14</output>

<gadget id="calculator">3 / 14</gadget>
<output>3/14 = around 0.214286</output>

<result>3/14 = around 0.214286</result>
