2)0,016-0,0125=0,0035

3)0,95-0,125=0,825

4)2,3+4210=4212,3

Answer 2

Sure, let's solve these expressions step by step using long division.

1) $0.004 : 0.25 - 0.2 : 16$:

First, divide $0.004$ by $0.25$:

markdownCopy code
   0.016
---------
0.25 | 0.004
   - 0
   -----
     0

Next, divide $0.2$ by $16$:

markdownCopy code
   0.0125
---------
  16 | 0.2
     - 0
   -----
     0.2
   - 0.192
   -------
     0.008

Finally, subtract $0.016$ and $0.0125$:

$0.016 - 0.0125 = 0.0035$

2) $0.5415 : 0.57 - 0.003 : 0.024$:

First, divide $0.5415$ by $0.57$:

markdownCopy code
   0.95
---------
0.57 | 0.5415
   - 0.57
   -------
    0.0415

Next, divide $0.003$ by $0.024$:

markdownCopy code
   0.125
---------
0.024 | 0.003
   - 0
   -----
   0.003
   - 0.003
   -------
     0

Finally, subtract $0.95$ and $0.125$:

$0.95 - 0.125 = 0.825$

3) $28.29 : 12.3 + 269.44 : 0.064$:

First, divide $28.29$ by $12.3$:

markdownCopy code
   2.3
---------
12.3 | 28.29
   - 24.6
   -------
     3.69

Next, divide $269.44$ by $0.064$:

markdownCopy code
   4210
---------
 0.064 | 269.44
      - 256
   -------
     13.44

Finally, add $2.3$ and $4210$:

$2.3 + 4210 = 4212.3$

So, the solutions to the given expressions are:

1. $0.004 : 0.25 - 0.2 : 16 = 0.0035$

2. $0.5415 : 0.57 - 0.003 : 0.024 = 0.825$

3. $28.29 : 12.3 + 269.44 : 0.064 = 4212.3$
