65⋅(812+8)=26  26 pints of blue paint are needed.  Explanation:  65 is the total amount of paint used. The ratio of blue to red is 8:12. The ratio can be simplified to 2 pints of blue for every 3 pints of red. So 25 pints are blue, 35 pints are red.   Multiply the fraction of pints of blue by the total number of pints.  65⋅(25)=26  26 being the number of pints of blue paint.   For red paint, you would do  65⋅(35)=39  To check if we are correct,  26+39=65  26:39→2613:3913→2:3.
