Question

(-15,64:4 3/5+7,1)*2 2/5 Мона решение?

Answer 1

-15,64:4 3/5=-15,64:4,6=-3, 4

-3,4+7.1=3.7

3.7*2 2\5=3.7*2.4=8.88

Answer 2

To solve the expression, let's start by simplifying it step by step. The expression you provided is:

(-15 + 64:4 + 3/5 + 7,1) * 2 2/5

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

1. 64:4 = 16 (division)
2. 16 + 3/5 = 16 + 0.6 = 16.6 (addition)
3. 16.6 + 7.1 = 23.7 (addition)

Now, the expression becomes:

(-15 + 23.7) * 2 2/5

Next, let's simplify the expression within the new parentheses:

1. -15 + 23.7 = 8.7 (addition)

Now, the expression becomes:

(8.7) * 2 2/5

Finally, let's multiply by the mixed number (2 2/5):

1. 2 * 8.7 = 17.4 (multiplication)
2. 2/5 * 8.7 = 3.48 (multiplication)

Now, the expression becomes:

17.4 + 3.48

Finally, we add the two results:

17.4 + 3.48 = 20.88

So, the solution to the expression is approximately 20.88.
