Answer 1

Задание: решить по действиям.

(3,2:4+4 4/5:3,2)×4,8=11 1/25

1. 3,2÷4=32/10÷4=16/5÷4=16×1/4×5=16/20=4/5=0,8

2. 4 4/5÷3,2 = 24/5÷32/10=24/5÷16/5= 24×5/5×16=24/16=3/2=1,5

3. 0,8+1,5=2,3

4. 2,3×4,8=23/10×48/10=23/10×24/5=23×24/10×5=23×12/5×5=276/25=11 1/25=11,04

Answer 2

I can help you with this math problem. Here is the detailed solution:

(3,2:4+4+4/5:3,2+)×4,8

First, we need to convert the commas to decimal points, since they are used as decimal separators in some languages. We get:

(3.2:4+4+4/5:3.2+)×4.8

Next, we need to interpret the colon symbol (:), which can mean either division or ratio. In this case, it seems to mean division, since there are no units given. So we rewrite the expression using the division symbol (/):

(3.2/4+4+4/5/3.2+)×4.8

Now, we need to apply the order of operations, which is parentheses, exponents, multiplication and division, and addition and subtraction. We start with the parentheses:

(3.2/4+4+4/5/3.2+)×4.8 = (0.8+4+0.8/3.2+)×4.8

Then, we do the multiplication and division from left to right:

(0.8+4+0.8/3.2+)×4.8 = (0.8+4+0.25)×4.8 = (5.05)×4.8

Finally, we do the addition and subtraction from left to right:

(5.05)×4.8 = 24.24

Therefore, the answer is 24.24.
