Answer 2

To add the two given mixed numbers, we need to first convert them to improper fractions and then find a common denominator.

Converting the first mixed number, 8 3/4, to an improper fraction:

8 3/4 = (8 * 4 + 3) / 4 = 35/4

Converting the second mixed number, 2 7/8, to an improper fraction:

2 7/8 = (2 * 8 + 7) / 8 = 23/8

Now, we have 35/4 plus 23/8. To find a common denominator, we can multiply the denominators together: 4 * 8 = 32.

Now, we'll convert the fractions to have a common denominator of 32:

35/4 = (35/4) * (8/8) = 280/32 23/8 = (23/8) * (4/4) = 92/32

Now we can add the fractions:

280/32 + 92/32 = (280 + 92) / 32 = 372/32

The fraction 372/32 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 4:

372/32 = (372/4) / (32/4) = 93/8

Therefore, 8 3/4 plus 2 7/8 equals 93/8 or 11 5/8 in mixed number form.
