Question 142369

{{{(3/2d^2)+4/3d}}}  We want to get a "Lowest Common Denominator (LCD)" for these two fractions.  The LCD is the smallest number that both 2d^2 and 3d will divide evenly into.  By inspection, we can see that the LCD is 6d^2.  We'll now multiply each term by 6d^2/6d^2 (which equals 1) and when we do that we will have reduced the expression to one fraction instead of two.  When we do this we get:

{{{(9+8d)/6d^2}}} 


Hope this helps---ptaylor
