A, B, and C cooperate to produce a batch of machine parts. Half of the parts produced by A are equal to (3/5) of the parts produced by B, which is also equal to three-quarters of the parts produced by C. The ratio of B is known. C produces 50 more parts, how many parts are there in this batch?
甲、乙、丙三人合作生产一批机器零件，甲生产的零件数量的一半与乙生产的零件的(3/5)相等，又等于丙生产零件数量的四分之三，已知乙比丙多生产50个零件，求这批零件共有多少个．
<gadget id="calculator">5 / 6</gadget>
<output>5/6 = around 0.833333</output>

<gadget id="calculator">2 / 3</gadget>
<output>2/3 = around 0.666667</output>

<gadget id="calculator">(5/6) - (2/3)</gadget>
<output>1/6 = around 0.166667</output>

<gadget id="calculator">50 / (1/6)</gadget>
<output>300</output>

<gadget id="calculator">300 * (5/6)</gadget>
<output>250</output>

<gadget id="calculator">300 * (2/3)</gadget>
<output>200</output>

<gadget id="calculator">300 + 250 + 200</gadget>
