the easiest trick for this one is to find the least common denominator (lcd)<br />Do were looking for a number that is a multiple of all the denominators.<br /><br />in this case, it's 120.<br />then you can divide 120 by the denominators and multiply by their numerators.<br /><br />showing the first one,120/ 3x 1=40<br /><br />the first fraction is 40/120<br /><br />let's go back to the question with our modified fractions<br />a. 40/120<br />b.45/120<br />c.48/120<br />d.60/120<br /><br />we can now tell that 60/120 or 1/2 is the greatest one
