If the two sides of a right triangle are (1/9) decimeter and (1/8) decimeter respectively, what is the area of the triangle in square decimeters?
一个直角三角形的两条直角边分别是(1/9)分米和(1/8)分米，这个三角形的面积是多少平方分米．
<gadget id="calculator">1 / 9</gadget>
<output>1/9 = around 0.111111</output>

<gadget id="calculator">1 / 8</gadget>
<output>1/8 = around 0.125</output>

<gadget id="calculator">(1/8) / 2</gadget>
<output>1/16 = around 0.0625</output>

<gadget id="calculator">(1/9) * (1/16)</gadget>
<output>1/144 = around 0.006944</output>

<result>1/144 = around 0.006944</result>
