Smiling and reading a 200-page storybook, I read (2/5) of the whole book on the first day, and the rest (3/4) on the second day. How many pages did I read on the second day?
笑笑看一本书200页的故事书，第一天看了全书的(2/5)，第二天看了余下的(3/4)，第二天看了多少页？
<gadget id="calculator">2 / 5</gadget>
<output>2/5 = around 0.4</output>

<gadget id="calculator">1 - (2/5)</gadget>
<output>3/5 = around 0.6</output>

<gadget id="calculator">3 / 4</gadget>
