Answers:
A) 2 / 5	B) 1 / 6	C) 1 / 3	D) 1 / 9	E) 2 / 6
<gadget id="calculator">1 / 30</gadget>
<output>1/30 = around 0.033333</output>

<gadget id="calculator">1 / 45</gadget>
<output>1/45 = around 0.022222</output>

<gadget id="calculator">(1/30) + (1/45)</gadget>
<output>1/18 = around 0.055556</output>

<gadget id="calculator">6 * (1/18)</gadget>
<output>1/3 = around 0.333333</output>

<result>C</result>

multiply(6, add(divide(const_1, 30), divide(const_1, 45)))
"a ' s one day ' s work = 1 / 30 b ' s one day ' s work = 1 / 45 ( a + b ) ' s one day ' s work = 1 / 30 + 1 / 45 = 1 / 18 the part of the work completed in 6 days = 6 ( 1 / 18 ) = 1 / 3 . answer c"
