Answer 2

To calculate this expression, you can follow these steps:

1. Add 1/4 to 5 3/4: 5 3/4 + 1/4 = 6 3/4

2. Subtract 1/12 from 4 5/12: 4 5/12 - 1/12 = 4 4/12 - 1/12 = 4 1/3

3. Multiply the results from steps 1 and 2: (6 3/4) * (4 1/3)

To multiply these mixed numbers, first convert them to improper fractions:

6 3/4 = (46 + 3)/4 = 27/4 4 1/3 = (34 + 1)/3 = 13/3

Now, multiply the fractions:

(27/4) * (13/3)

To multiply fractions, multiply the numerators together and the denominators together:

(27 * 13) / (4 * 3) = 351/12

Now, simplify the fraction:

351/12 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 3:

(351 ÷ 3) / (12 ÷ 3) = 117/4

So, the final result is 117/4, which can also be expressed as a mixed number:

117/4 = 29 1/4

Therefore, the answer to the expression is 29 1/4.
