Answer 2

To simplify the expression (1/3)^2 + 5 3/4 : (-1/2)^2, follow these steps:

Step 1: Square the fractions: (1/3)^2 = 1/9 (-1/2)^2 = 1/4

Step 2: Calculate the division of 5 3/4 by 1/4: To divide a mixed number by a fraction, convert the mixed number to an improper fraction and then divide.

5 3/4 = (4*5 + 3)/4 = (20 + 3)/4 = 23/4

Now, divide 23/4 by 1/4: (23/4) / (1/4) = (23/4) * (4/1) = 23

Step 3: Add the results from Step 1 and Step 2: (1/9) + 23 = 1/9 + 207/9 = (1 + 207)/9 = 208/9

So, (1/3)^2 + 5 3/4 : (-1/2)^2 = 208/9.
