Question 1197791
<br>
It is not necessary to write an algebraic equation showing the proportion and solve the equation to get the answer.  However, that method of solving the problem might be preferred by some students.<br>
An alternative method is simply to multiply the weight on earth by the given ratio:<br>
{{{160*(11/3)=1760/3}}}<br>
ANSWER: 1760/3 pounds, or 586 2/3 pounds<br>
Practice using both methods (and any other method you might see) and find the one that "works" for you.<br>
