Answer 2

To perform the calculation, you need to find a common denominator for the fractions and then add them together:

Step 1: Find the common denominator: The least common multiple (LCM) of 1 and 21 is 21.

Step 2: Convert the fractions to have a common denominator of 21: 2/1 = 2 * 21/1 * 21 = 42/21 4/21 (already in the desired form)

Step 3: Add the fractions together: 42/21 + 4/21 = 46/21

So, the result of the calculation is 46/21.
