I have read 130 pages of a book, and I plan to read the rest in 8 days. If the number of pages I read every day is equal, and the number of pages I read in 3 days is exactly the whole book (5/22), how many pages does this book have?
一本书，已看了130页，剩下的准备8天看完，如果每天看的页数相等，3天看的页数恰好是全书的(5/22)，这本书共有多少页？
<gadget id="calculator">5 / 22</gadget>
<output>5/22 = around 0.227273</output>

<gadget id="calculator">3 / 8</gadget>
<output>3/8 = around 0.375</output>

<gadget id="calculator">(5/22) / (3/8)</gadget>
<output>20/33 = around 0.606061</output>

<gadget id="calculator">1 - (20/33)</gadget>
<output>13/33 = around 0.393939</output>

<gadget id="calculator">130 / (13/33)</gadget>
<output>330</output>

<result>330</result>
