Пошаговое объяснение:

4. 4/7 - 1. 3/8 = 4. 32/56 - 1. 21/56 =

3. 11/56

2. 1/2 - 1. 3/4 = 2. 2/4 - 1. 3/4 = 1. 6/4

- 1. 3/4 = 3/4

2. 4/7 : 2. 6/2 = 18/7 : 10/2 = 18/7 * 2/10 = 36/70 = 18/35

Answer 3

Calculation Explanation

To solve the expression 4 4/7 - 1 3/8 + 2 1/2 - 1 3/4 + 2 4/7 : 2 6/2, we need to follow the order of operations (PEMDAS/BODMAS).

1. First, we need to perform any division or multiplication from left to right. In this case, we have a division operation: 2 4/7 : 2 6/2. 2. Next, we need to perform any addition or subtraction from left to right. In this case, we have multiple addition and subtraction operations: 4 4/7 - 1 3/8 + 2 1/2 - 1 3/4.

Let's solve the division operation first:

2 4/7 : 2 6/2

To divide fractions, we need to multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is obtained by swapping the numerator and denominator.

Converting the mixed numbers to improper fractions:

2 4/7 = (2 * 7 + 4)/7 = 18/7

2 6/2 = (2 * 2 + 6)/2 = 10/2 = 5

Now, we can perform the division:

18/7 : 5 = 18/7 * 1/5 = 18/35

Now, let's solve the addition and subtraction operations:

4 4/7 - 1 3/8 + 2 1/2 - 1 3/4

Converting the mixed numbers to improper fractions:

4 4/7 = (4 * 7 + 4)/7 = 32/7

1 3/8 = (1 * 8 + 3)/8 = 11/8

2 1/2 = (2 * 2 + 1)/2 = 5/2

1 3/4 = (1 * 4 + 3)/4 = 7/4

Now, we can perform the addition and subtraction:

32/7 - 11/8 + 5/2 - 7/4

To add or subtract fractions, we need to have a common denominator. In this case, the common denominator is 8.

Converting the fractions to have a common denominator:

32/7 = (32/7) * (8/8) = 256/56

11/8 = (11/8) * (7/7) = 77/56

5/2 = (5/2) * (4/4) = 20/8

7/4 = (7/4) * (2/2) = 14/8

Now, we can perform the addition and subtraction:

256/56 - 77/56 + 20/8 - 14/8

Combining the fractions:

(256 - 77 + 20 - 14)/56

Simplifying the numerator:

185/56

Therefore, the result of the expression 4 4/7 - 1 3/8 + 2 1/2 - 1 3/4 + 2 4/7 : 2 6/2 is 185/56.

Answer

The result of the expression 4 4/7 - 1 3/8 + 2 1/2 - 1 3/4 + 2 4/7 : 2 6/2 is 185/56.
