I read an extra-curricular book with a smile. I read (1/6) of the whole book on the first day, and the rest (1/4) on the second day. I read a total of 54 pages in two days. How many pages does this book have?
笑笑看一本课外书，第一天看了全书的(1/6)，第二天看来剩下的(1/4)，两天共看了54页．这本书共有多少页？
<gadget id="calculator">1 / 6</gadget>
<output>1/6 = around 0.166667</output>

<gadget id="calculator">1 - (1/6)</gadget>
<output>5/6 = around 0.833333</output>

<gadget id="calculator">1 / 4</gadget>
<output>1/4 = around 0.25</output>

<gadget id="calculator">(5/6) * (1/4)</gadget>
<output>5/24 = around 0.208333</output>

<gadget id="calculator">(1/6) + (5/24)</gadget>
<output>3/8 = around 0.375</output>

<gadget id="calculator">54 / (3/8)</gadget>
<output>144</output>
