To find what should be added to 3 times 39 to get 12 times 39, we can set up an equation.

Let's represent the unknown value to be added as "x".

3 times 39 + x = 12 times 39

Now, let's solve for "x":

3 * 39 + x = 12 * 39

117 + x = 468

Subtract 117 from both sides to isolate "x":

x = 468 - 117

x = 351

So, 351 should be added to 3 times 39 to get 12 times 39.
