Answer 1

насколько я понял , то так :

1) 1427\56 или 25  27\56

2) 880550

Answer 2

Let's break down the expression step by step:

1. 5 1/7 is a mixed number, which can be converted to an improper fraction: 5 1/7 = (7 * 5 + 1) / 7 = 36/7

2. Now, let's perform the subtraction: 36/7 - 3

To subtract fractions, we need a common denominator, which is 7 in this case: (36/7) - (3 * 7/7) (36/7) - (21/7)

Now, subtract the fractions: (36 - 21) / 7 15/7

3. Next, let's simplify the fraction 15/7: 15/7 can be expressed as a mixed number: 15/7 = 2 1/7

4. Now, let's move on to the division: (2 1/7) ÷ (4/35)

To divide fractions, we invert the second fraction and multiply: (2 1/7) * (35/4)

To multiply mixed numbers, convert them to improper fractions: 2 1/7 = (7 * 2 + 1) / 7 = 15/7

Now, multiply the fractions: (15/7) * (35/4)

5. Multiplication of fractions: (15 * 35) / (7 * 4)

Now, perform the multiplication in the numerator and denominator: (525) / (28)

6. Reduce the fraction to its simplest form: 525 ÷ 28 = 18.75

So, the result of the expression is approximately 18.75.

7. Now, let's move on to the next part of the expression: (8.8 * 10^3) + (5.5 * 10^2)

In scientific notation, 10^3 means multiplying by 1000, and 10^2 means multiplying by 100.

(8.8 * 1000) + (5.5 * 100)

Now, perform the multiplications: 8800 + 550

8. Finally, add the numbers: 8800 + 550 = 9350

So, the result of the second part of the expression is 9350.

Now, we have the two results:

1. 15/7 ≈ 2.1429
2. 9350
