Question 1145856
<br>
The pirate ship makes one complete circle every 32/12 = 8/3 days.<br>
The merchant ship makes one complete circle every 48/8 = 6 days.<br>
The number of days until they are again at the same point is the least common multiple of 8/3 and 6.<br>
It's a bit unusual to need to find the LCM of two numbers where one of them is a fraction.  So let me show the way I prefer for finding the least common multiple of ANY two numbers.<br>
(1) Make a fraction with the two numbers as the numerator and denominator:<br>
{{{(8/3)/6}}}<br>
(2) Simplify the fraction to where the numerator and denominator are whole numbers with no common factor:<br>
{{{(8/3)/6 = 8/18 = 4/9}}}<br>
(3) Write the equation that says the original fraction and the simplified fractions are equivalent:<br>
{{{(8/3)/6 = 4/9}}}<br>
(4) Cross multiplying in either direction will give you the LCM:<br>
{{{(8/3)*9 = 8*3 = 24}}}
{{{6*4 = 24}}}<br>
So the least common multiple of 8/3 and 6 is 24.<br>
ANSWER C: 24 days
