well to solve this problem is to put 3.69 and 0.3 in an algorithm. Step #2 you move the decimal one spot to the right. Step 3# you divide 36.9/3. Then your answer would be 12.3 hope that helped.

Alright, so we have 3.69/0.3. What I personally like to do is expand it so we have whole numbers, so we can multiply the equation by 100/100 to get 
369/30. 


and we know that 30 goes into 300 10 times due to that you simply add another 0. After that, we're left with 369-300=69. We know that 30*2=60, and 69-60=9. Therefore, we can add the 10 and the 2 up to get 12, and the remainder is therefore 9. 

The answer is therefore 12+9/30., or 12+3/10 by simplifying the fraction by dividing both the numerator and denominator by 3
