I typed 45 pages of a manuscript on the first day, and typed 20% more on the second day than on the first day. In two days, I typed 60% of the manuscript. How many pages does this manuscript have?
打一本书稿第一天打了45页，第二天比第一天多打了20%，两天共打了这本书稿的60%，问这本书稿共有多少页？
<gadget id="calculator">20 / 100</gadget>
<output>1/5 = around 0.2</output>

<gadget id="calculator">1 + (1/5)</gadget>
<output>6/5 = around 1.2</output>

<gadget id="calculator">45 * (6/5)</gadget>
<output>54</output>

<gadget id="calculator">45 + 54</gadget>
<output>99</output>

<gadget id="calculator">60 / 100</gadget>
<output>3/5 = around 0.6</output>

<gadget id="calculator">99 / (3/5)</gadget>
<output>165</output>
