Answer 2

Let's break down the expression step by step:

(39 + 49) ÷ 11.6 × (58 - 45).12 × 4 + (90 - 38).99 ÷ 33 - 72 ÷ 24

First, let's simplify the parentheses:

(39 + 49) ÷ 11.6 × 13.12 × 4 + 52.99 ÷ 33 - 72 ÷ 24

Next, let's perform the addition and subtraction inside the parentheses:

88 ÷ 11.6 × 13.12 × 4 + 52.99 ÷ 33 - 72 ÷ 24

Now, let's perform the multiplications and divisions from left to right:

7.5862 × 13.12 × 4 + 52.99 ÷ 33 - 72 ÷ 24

99.749664 × 4 + 52.99 ÷ 33 - 72 ÷ 24

398.998656 + 1.606667 - 3

Now, let's perform the remaining additions and subtractions:

400.605323 - 1.393333

The result is approximately 399.21199.

Therefore, (39 + 49) ÷ 11.6 × (58 - 45).12 × 4 + (90 - 38).99 ÷ 33 - 72 ÷ 24 is approximately equal to 399.21199.
