a satellite is composed of 30 modular units, each of which is equipped with a set of sensors, some of which have been upgraded. each unit contains the same number of non - upgraded sensors. if the number of non - upgraded sensors on one unit is 1 / 6 the total number of upgraded sensors on the entire satellite, what fraction of the sensors on the satellite have been upgraded?  Choose the correct choice from the following options:
A) 5 / 6
B) 1 / 5
C) 1 / 6
D) 1 / 7
E) 1 / 24
<gadget id="calculator">1 / 6</gadget>
<output>1/6 = around 0.166667</output>

<gadget id="calculator">(1/6) * 30</gadget>
<output>5</output>

<gadget id="calculator">30 * 5</gadget>
<output>150</output>

<gadget id="calculator">30 + 150</gadget>
<output>180</output>

<gadget id="calculator">30 / 180</gadget>
<output>1/6 = around 0.166667</output>

divide(30, add(30, multiply(30, multiply(divide(1, 6), 30))))
"let x be the number of upgraded sensors on the satellite . the number of non - upgraded sensors per unit is x / 6 . the number of non - upgraded sensors on the whole satellite is 30 ( x / 6 ) = 5 x . the fraction of sensors which have been upgraded is x / ( x + 5 x ) = x / 6 x = 1 / 6 the answer is c ."
