Answer 3

To simplify the given expression, let's break it down step by step:

First, let's simplify the addition within parentheses: (213/48 + 25/12) = (4.4375 + 2.0833) = 6.5208

Next, let's simplify the remaining addition and subtraction: 6.5208 + 3 3/4 - 93/4 + 12

To add fractions, we need a common denominator. Let's convert the mixed numbers to improper fractions: 3 3/4 = (4 * 3 + 3) / 4 = 15/4 12 = 12/1

Now, let's find a common denominator for 4, 15, and 1, which is 60: 6.5208 + 15/4 - 93/4 + 12/1 = 6.5208 + (15 * 15)/(4 * 15) - (93 * 15)/(4 * 15) + (12 * 60)/(1 * 60) = 6.5208 + 225/60 - 1395/60 + 720/60

Now that we have a common denominator, we can add and subtract the fractions: = 6.5208 + (225 - 1395 + 720) / 60 = 6.5208 + (-450) / 60 = 6.5208 - 7.5 = -0.9792

Therefore, the simplified value of the expression (213/48 + 25/12) + 3 3/4 - 93/4 + 12 is approximately -0.9792.
