Answer 2

To simplify the given expression, let's perform the calculations step by step:

First, let's simplify the addition and subtraction of mixed numbers:

(13 - 8) + (9/10) + (26 - 15) + (1/2) - (14 - 7) + (1/5) + (3 + 8) + (3/10) + (1/2)

Simplifying each operation within the brackets:

5 + (9/10) + 11 + (1/2) + 7 + (1/5) + 11 + (3/10) + (1/2)

Now, let's combine the whole numbers and fractions separately:

Whole numbers: 5 + 11 + 7 + 11 = 34

Fractions: (9/10) + (1/2) + (1/5) + (3/10) + (1/2)

To add fractions, we need a common denominator. The common denominator for 10, 2, 5, and 10 is 10:

[(9/10) + (1/2) + (1/5) + (3/10) + (1/2)] = [(9/10) + (5/10) + (2/10) + (3/10) + (5/10)]

Now we can add the fractions:

[(9 + 5 + 2 + 3 + 5)/10] = (24/10)

Simplifying the fraction:

(24/10) = (12/5)

Finally, let's add the whole numbers and fractions:

34 + (12/5)

To add a whole number and a fraction, we need to convert the whole number into a fraction with a denominator of 5:

34 = (34/1)

Now we can add the fractions:

(34/1) + (12/5)

To add fractions, we need a common denominator. The common denominator for 1 and 5 is 5:

[(34/1) + (12/5)] = [(34/1) + (12/5)]

Now we can add the fractions:

[(345 + 121)/5] = (170 + 12)/5 = 182/5

Therefore, the simplified result of the expression is 182/5 or 36 2/5.
