Answer 2

To solve the given equation, we need to find a common denominator for the fractions and then add them together.

The denominators are 28 and 21. The smallest number that both 28 and 21 divide into evenly is 84.

Now let's convert the fractions to have a denominator of 84:

12/28 = (12 * 3)/(28 * 3) = 36/84

14/21 = (14 * 4)/(21 * 4) = 56/84

Now we can add the fractions:

36/84 + 56/84 = (36 + 56)/84 = 92/84

To simplify this fraction, we can divide the numerator and denominator by their greatest common divisor (GCD), which is 4:

92/84 = (92/4)/(84/4) = 23/21

So, the sum of 12/28 and 14/21 is 23/21.
