Answer 2

Ответ:

-5/8 (3,2- 1 3/5)-7,2(-4/9+2,5)=−15,175

Answer 3

To simplify the expression:

-5/8(3,2 - 1 3/5) - 7.2(-4/9 + 2.5)

First, let's simplify the terms inside the parentheses:

3.2 - 1 3/5 = 3.2 - (1 + 3/5) = 3.2 - 1 - 3/5 = 2.2 - 3/5

Now, we'll find a common denominator for the subtraction:

2.2 - 3/5 = (11/5) - (3/5) = 11/5 - 3/5

Now, let's simplify the terms inside the second set of parentheses:

-4/9 + 2.5 = -4/9 + 2.5*(9/9) = -4/9 + 22.5/9 = (-4 + 22.5)/9

Now, we have:

-5/8(2.2 - 3/5) - 7.2((-4 + 22.5)/9)

Next, simplify each part separately:

-5/8(2.2 - 3/5) = -5/8 * (11/5 - 3/5) = -5/8 * (8/5) = -40/40 = -1

-7.2((-4 + 22.5)/9) = -7.2 * (18.5/9) ≈ -7.2 * 2.0556 ≈ -14.8333

Now, subtract the second result from the first:

-1 - (-14.8333) = -1 + 14.8333 ≈ 13.8333

So, the simplified result of the expression is approximately 13.8333.
