Answer 1

Ответ:

..............................=9,782

1)   12,61008 :5,04=2,3352

2)   79,235:6,5=12,19

3)   2,3352+12,19=14,5252

4)   14,5252*6 1/2=14,5252*6,5=94,4138

5)   94,4138 - ( -4,502)=94,4138+4,502=98,9158

6)   512,9:25=20,516

7)   -108,405 :6 3/5= - 108,405 : 6,6= - 16,425

8)   266,84:78=3,42

9)   - 16,425 +3,42= - 13,005

10)   -13,005:1,25= - 10,404

11)   20,516+( -10,404)=20,516 - 10,404=10,112

12)   98,9158 : 10 112=9,782

Answer 2

To simplify this expression, let's break it down step by step:

1. (12,61008:5 1/25 + 79,235:6,5)
2. • 6 1/2
3. • 4,502
4. • (1:1/40)
5. : (1:0,05)

Let's start with each part:

1. (12,61008:5 1/25 + 79,235:6,5) First, let's simplify each term within the parentheses:

   12,61008:5 = 2,522016 79,235:6,5 = 12,188461538461538

   Now, add these two values together:

   2,522016 + 12,188461538461538 ≈ 14.710477538461538

2. • 6 1/2 The symbol • represents multiplication. So, multiply 14.710477538461538 by 6 1/2:

   14.710477538461538 * (6 + 1/2) = 14.710477538461538 * 6.5 ≈ 95.28285500000001

3. • 4,502 Add 4,502 to the result from step 2:

   95.28285500000001 + 4.502 ≈ 99.78585500000001

4. • (1:1/40) Divide 1 by 1/40 (which is equivalent to multiplying by 40):

   1 / (1/40) = 1 * 40 = 40

   Now, subtract 40 from the result of step 3:

   99.78585500000001 - 40 = 59.78585500000001

5. : (1:0,05) Divide 1 by 0.05:

   1 / 0.05 = 20

   Now, divide the result from step 4 by 20:

   59.78585500000001 / 20 ≈ 2.9892927500000005

So, the final simplified value is approximately 2.9892927500000005.
