Answer 2

Calculating Fractions

To calculate the given fractions, we can follow these steps:

1. Convert mixed numbers to improper fractions: - 2 1/3 = (2 * 3 + 1) / 3 = 7/3 - 2 2/5 = (2 * 5 + 2) / 5 = 12/5

2. Perform the operations: - 3/4 - 5/16 + 1/8 + 7/3 + 5/6 - 12/5

Solution

First, let's convert the mixed numbers to improper fractions:

- 2 1/3 = 7/3 - 2 2/5 = 12/5

Now, we can perform the operations:

- 3/4 - 5/16 + 1/8 + 7/3 + 5/6 - 12/5

To add or subtract fractions, we need to find a common denominator. In this case, the common denominator is 48.

- 3/4 = 36/48 - 5/16 = 15/48 - 1/8 = 6/48 - 7/3 = 112/48 - 5/6 = 40/48 - 12/5 = 115/48

Now, we can perform the operations:

36/48 - 15/48 + 6/48 + 112/48 + 40/48 - 115/48

= (36 - 15 + 6 + 112 + 40 - 115) / 48

= 74/48

= 37/24

So, the result of the calculation is 37/24.
