Answer 2

2,5 + 4,6 * (13 4/3 - 12 13/17)= 9.71568627451

Answer 3

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

First, let's simplify the expression inside the parentheses: 13 4/3 - 12 13/17

To subtract mixed numbers, we need to convert them into improper fractions: 13 4/3 = (13 * 3 + 4)/3 = 43/3 12 13/17 = (12 * 17 + 13)/17 = 205/17

Now we can subtract the fractions: 43/3 - 205/17

To subtract fractions, we need to find a common denominator: The common denominator is 3 * 17 = 51

Now let's rewrite the fractions with the common denominator: (43/3) * (17/17) - (205/17) * (3/3) = (731/51) - (615/51) = (731 - 615)/51 = 116/51

Now, let's substitute this value back into the original expression: 2.5 + 4.6 * (116/51)

Now, we can calculate the expression: = 2.5 + 4.6 * (116/51) = 2.5 + (4.6 * 116)/51 = 2.5 + 531.2/51 = 2.5 + 10.4156862745 = 12.9156862745

Therefore, 2.5 + 4.6 * (13 4/3 - 12 13/17) is approximately equal to 12.9157.
