Answer 2

To solve the expression (3 + 1/2 : 4 + 2/3 + 4 + 2/3 : 3 + 1/2) * 4 + 4/5, we need to follow the order of operations (also known as PEMDAS or BODMAS). This means we need to perform the operations inside parentheses first, then any multiplication or division from left to right, and finally any addition or subtraction from left to right.

Let's break down the expression step by step:

1. Inside the parentheses, we have the expression 3 + 1/2 : 4 + 2/3 + 4 + 2/3 : 3 + 1/2. To simplify this, we need to evaluate the divisions first.

2. The division 1/2 : 4 can be simplified to 1/8.

3. The division 2/3 + 4 + 2/3 can be simplified to 10/3.

4. The division 3 + 1/2 can be simplified to 7/2.

Now, let's substitute these simplified values back into the original expression:

(3 + 1/8) * 4 + 4/5

Next, we need to perform the multiplication and addition from left to right:

1. 3 + 1/8 = 25/8

2. (25/8) * 4 = 100/8 = 25/2

3. 25/2 + 4/5 = (125/10) + (8/10) = 133/10

Therefore, the value of the expression (3 + 1/2 : 4 + 2/3 + 4 + 2/3 : 3 + 1/2) * 4 + 4/5 is 133/10.

Please note that the answer is given in fractional form. If you prefer a decimal approximation, you can divide 133 by 10 to get approximately 13.3.

I hope this helps! Let me know if you have any further questions.
