Answer 2

Sure, I'd be happy to help you with these calculations. Let's break down each expression step by step:

A) 3 + 1/3 + 5 + 7/12:

To add fractions, we need to find a common denominator. In this case, the common denominator is 12.

Converting the mixed number 3 into an improper fraction, we have:

3 = 3/1

Now, let's add the fractions:

3/1 + 1/3 = (9/3) + 1/3 = 10/3

Next, we add the whole numbers and the remaining fractions:

10/3 + 5 + 7/12 = 10/3 + 15/3 + 7/12

To add fractions with different denominators, we need to find a common denominator. In this case, the common denominator is 12.

Multiplying the first fraction by 4/4 and the second fraction by 12/12, we get:

10/3 + 15/3 + 7/12 = 40/12 + 60/12 + 7/12

Now, we can add the fractions:

40/12 + 60/12 + 7/12 = (40 + 60 + 7)/12 = 107/12

So, the value of the expression 3 + 1/3 + 5 + 7/12 is 107/12.

B) 12 + 7/15 + 8 + 5/6:

For this expression, we can follow a similar process as above.

First, let's add the fractions:

7/15 + 5/6 = (14
