It takes 20 days for engineering team A to complete a road alone. After 5 days of work, I found that there are still 300 meters that have not been repaired. How many meters have been repaired?
一条公路，甲工程队独修要20天才能完工．做了5天后发现还有300米没修，已修了多少米．
<gadget id="calculator">1 / 20</gadget>
<output>1/20 = around 0.05</output>

<gadget id="calculator">(1/20) * 5</gadget>
<output>1/4 = around 0.25</output>

<gadget id="calculator">1 - (1/4)</gadget>
<output>3/4 = around 0.75</output>

<gadget id="calculator">300 / (3/4)</gadget>
<output>400</output>

<gadget id="calculator">400 - 300</gadget>
<output>100</output>

<result>100</result>
