Naughty reading a 140-page story book, I read the whole book (1/5) on the first day, and the rest (2/7) on the second day, which page should I start reading on the third day?

<gadget id="calculator">1 / 5</gadget>

<gadget id="calculator">140 * (1/5)</gadget>

<gadget id="calculator">112 * (2/7)</gadget>
