中华机床厂要加工一批机床，原计划每天加工80台，15天完成，由于技术革新，实际每天比原计划多加工50%，实际用多少天完成任务？(用比例知识解)
<gadget id="calculator">80 * 15</gadget>
<output>1_200</output>

<gadget id="calculator">50 / 100</gadget>
<output>1/2 = around 0.5</output>

<gadget id="calculator">80 * (1/2)</gadget>
<output>40</output>

<gadget id="calculator">80 + 40</gadget>
<output>120</output>

<gadget id="calculator">1_200 / 120</gadget>
<output>10</output>
