Answer 2

To solve the expression you've provided:

11,25 - 35/12 + 4,3 - 719/30 ÷ (77/12 - 55/6)

Let's break it down step by step:

First, we'll simplify the division:

77/12 - 55/6 = (77/12) - (110/12) = (77 - 110)/12 = -33/12 = -11/4

Now, we substitute this result back into the original expression:

11,25 - 35/12 + 4,3 - 719/30 ÷ (-11/4)

Next, let's simplify the division:

719/30 ÷ (-11/4) = (719/30) ÷ (-11/4) = (719/30) × (-4/11) = -2876/330 = -1438/165

Now, substitute this result back into the expression:

11,25 - 35/12 + 4,3 - (-1438/165)

We'll simplify the subtraction by multiplying -1 to the numerator of the fraction:

11,25 - 35/12 + 4,3 + 1438/165

Next, we'll find a common denominator for the fractions:

11,25 = 11,25 × 12/12 = 135/12 35/12 remains the same 4,3 = 4,3 × 12/12 = 51,6/12 1438/165 remains the same

Now, we can combine the fractions:

135/12 - 35/12 + 51,6/12 + 1438/165

Combining the numerators:

(135 - 35 + 51,6 + 1438)/12

Adding the numerators:

(151.6 + 1438)/12 = 1589.6/12

Dividing the numerator by the denominator:

1589.6 ÷ 12 = 132.4666667

Rounding to a reasonable decimal place:

132.47

Therefore, the final result is approximately 132.47.
