Answer 2

To add the fractions 7/12 and 13/18, you need to find a common denominator and then add the numerators. Here's how you can do it:

Step 1: Find the common denominator. The common denominator is the least common multiple (LCM) of the denominators, which in this case is 36.

Step 2: Convert the fractions to have the common denominator. To convert 7/12 to have a denominator of 36, you multiply the numerator and denominator by 3. So, 7/12 is equal to (73)/(123) = 21/36.

To convert 13/18 to have a denominator of 36, you multiply the numerator and denominator by 2. So, 13/18 is equal to (132)/(182) = 26/36.

Step 3: Add the numerators. Now that both fractions have the same denominator, you can add the numerators. 21/36 + 26/36 = (21 + 26)/36 = 47/36.

So, 7/12 + 13/18 = 47/36.
