 Hi and welcome to the session. I am Kanika and I am going to help you to solve the following question. The question says solve A part is 1 by 12 plus 1 by 12. In this question we have to add two light fractions. We should know that sum of two or more light fractions is equal to sum of numerators common denominator. Let's understand this by an example. If A by B and C by B are any two light fractions then there is sum that is A by B plus C by B is equal to A plus C by B. So light fractions are added by only adding the numerators and keeping the denominator as a test. This is the key idea in this question. Let's now begin with the solution. In this question we have to solve 1 by 12 plus 1 by 12. By the key idea we know that sum of two or more light fractions is equal to sum of numerators upon common denominator. So this means 1 by 12 plus 1 by 12 is equal to 1 plus 1 upon 12 and this gives us 2 by 12 and this is equal to 2 upon. Now 12 can be written as 2 into 6 can sync to from both numerator and denominator we are left with 1 by 6. So the required answer is 1 by 6. This completes the session. Bye and take care.
