Three workers, A, B, and C, work together to make a batch of parts. A processes 1/7 of the total number, which is 24 less than B. The ratio of the number of parts processed by B and C is 2:1. How many parts are there in total?
甲、乙、丙三名工人共同做一批零件，甲加工了总数的(1/7)，比乙少加工了24只，乙、丙加工零件数量的比是2：1．这批零件共有多少只？

<output>1/7 = around 0.142857</output>

<gadget id="calculator">(1/7) * (1/2)</gadget>
<output>1/14 = around 0.071429</output>

<gadget id="calculator">1 - (1/7) - (1/7) - (1/14)</gadget>
<output>9/14 = around 0.642857</output>
