Obviously, when reading a book, I read 35 pages on the first day and 70 pages on the second day. At this time, the ratio of the total number of pages read to the number of remaining pages is 3:2. How many pages does this book have?
明明看一本书，第一天看了35页，第二天看了70页，这时看了的总页数与剩下的页数的比是3：2，这本书有多少页？
<gadget id="calculator">35 + 70</gadget>

<output>5</output>

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

<gadget id="calculator">105 / (3/5)</gadget>
<output>175</output>

<result>175</result>
