Answer 3

To add or subtract mixed numbers like 4 1/2 and 6 3/4, we first need to find a common denominator.

The denominator of 2 in 4 1/2 is already a factor of 4, so we just need to convert 6 3/4 to an equivalent fraction with a denominator of 4:

6 3/4 = 6 + 3/4 = 6 + 3 * 1/4 = 6 + 3/4 = 24/4 + 3/4 = 27/4

Now, we can rewrite the mixed numbers with the common denominator of 4:

4 1/2 = 8/4 + 1/2 = 9/4 6 3/4 = 27/4

So, the problem becomes:

9/4 + 27/4

To add these fractions, we simply add their numerators and keep the denominator:

(9 + 27) / 4 = 36/4 = 9

Therefore, 4 1/2 : 6 3/4 = 9/4, or 2 1/4.
