Answer 2

To solve this expression, let's break it down step by step:

Step 1: Subtract 4 1/2 from 8 1/2 8 1/2 - 4 1/2 = (8 - 4) + (1/2 - 1/2) = 4 + 0 = 4

Step 2: Add the fractions 2 1/2 and 1 3/4 To add fractions, we need a common denominator. The common denominator for 2 and 4 is 4.

2 1/2 = 2 + 1/2 = 2 2/4 1 3/4 = 1 + 3/4 = 1 3/4

Now, we can add these fractions: 2 2/4 + 1 3/4 = 3 5/4

Step 3: Divide 4 by the result from Step 2 4 ÷ (3 5/4)

To divide by a fraction, we multiply by its reciprocal (flipping numerator and denominator): 4 ÷ (3 5/4) = 4 * (4/9)

Step 4: Simplify the final fraction To simplify 4 * (4/9), we multiply the whole number by the numerator of the fraction and then add it to the result: 4 * (4/9) = (4 * 4) / 9 = 16/9

So, the final answer is 16/9.
