一个长方体的铁块体积是(3/4)立方米．它的长是(4/5)米，宽是(8/15)米．这个长方体铁块的高是多少米？(列方程解答)
<gadget id="calculator">3 / 4</gadget>
<output>3/4 = around 0.75</output>

<gadget id="calculator">4 / 5</gadget>
<output>4/5 = around 0.8</output>

<gadget id="calculator">8 / 15</gadget>
<output>8/15 = around 0.533333</output>

<gadget id="calculator">(4/5) * (8/15)</gadget>
<output>32/75 = around 0.426667</output>

<gadget id="calculator">(3/4) / (32/75)</gadget>
<output>225/128 = around 1.757812</output>

<result>225/128 = around 1.757812</result>
