The little sloppy divides a number by (4/5) and miscalculates as multiplying (4/5), and the result is (1/5). What is the correct result of this question?
小马虎把一个数除以(4/5)，误算成乘(4/5)，结果是(1/5)，这道题的正确结果是多少．
<gadget id="calculator">1 / 5</gadget>
<output>1/5 = around 0.2</output>

<gadget id="calculator">4 / 5</gadget>
<output>4/5 = around 0.8</output>

<gadget id="calculator">(1/5) / (4/5) / (4/5)</gadget>
<output>5/16 = around 0.3125</output>

<result>5/16 = around 0.3125</result>
