Answer 2

To add the fractions (10 4/21) and (3 19/21), we need to convert the mixed numbers into improper fractions and then find a common denominator.

Let's start with the first mixed number, 10 4/21: 10 is the whole number, and 4/21 is the fractional part. To convert it to an improper fraction, we multiply the whole number (10) by the denominator of the fraction (21) and add the numerator (4). This gives us (10 * 21 + 4) / 21 = 214/21.

Now let's convert the second mixed number, 3 19/21: 3 is the whole number, and 19/21 is the fractional part. Following the same process, we get (3 * 21 + 19) / 21 = 82/21.

Now that both mixed numbers are converted into improper fractions, we can add them: 214/21 + 82/21 = (214 + 82) / 21 = 296/21.

The sum of (10 4/21) and (3 19/21) is 296/21.
