Answer 1

1. 29/6 - 29/12 = 29/12 = 2 5/12
2. 94/9 - 149/18 = 39/18 = 2 3/18 = 2 1/6
3. 19/2 - 9/4 = 29/4 = 7 1/4
4. 27/4 - 8/3 = 49/12 = 4 1/12

Answer 2

Solution:

To solve the given arithmetic expressions, let's simplify each expression step by step:

1) 4 целых 5/6 - 2 целых 5/12:

To subtract mixed numbers, we need to convert them into improper fractions and then perform the subtraction.

4 целых 5/6 can be written as (4 * 6 + 5)/6 = 29/6.

2 целых 5/12 can be written as (2 * 12 + 5)/12 = 29/12.

Now, we can subtract the fractions: (29/6) - (29/12).

To subtract fractions, we need to have a common denominator. In this case, the common denominator is 12.

(29/6) - (29/12) = (2 * 29 - 29)/12 = 29/12.

Therefore, the solution to the first expression is 29/12.

2) 10 цл 4/9 - 8 цл 5/18:

Following the same steps as above, we can convert the mixed numbers into improper fractions:

10 цл 4/9 = (10 * 9 + 4)/9 = 94/9.

8 цл 5/18 = (8 * 18 + 5)/18 = 149/18.

Now, we can subtract the fractions: (94/9) - (149/18).

To subtract fractions, we need to have a common denominator. In this case, the common denominator is 18.

(94/9) - (149/18) = (2 * 94 - 149)/18 = 39/18.

We can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 3.

39/18 = (39/3) / (18/3) = 13/6.

Therefore, the solution to the second expression is 13/6.

3) 9 цл 1/2 - 2 цл 1/4:

Converting the mixed numbers into improper fractions:

9 цл 1/2 = (9 * 2 + 1)/2 = 19/2.

2 цл 1/4 = (2 * 4 + 1)/4 = 9/4.

Now, we can subtract the fractions: (19/2) - (9/4).

To subtract fractions, we need to have a common denominator. In this case, the common denominator is 4.

(19/2) - (9/4) = (2 * 19 - 9)/4 = 29/4.

Therefore, the solution to the third expression is 29/4.

4) 6 цл 3/4 - 2 цл 2/3:

Converting the mixed numbers into improper fractions:

6 цл 3/4 = (6 * 4 + 3)/4 = 27/4.

2 цл 2/3 = (2 * 3 + 2)/3 = 8/3.

Now, we can subtract the fractions: (27/4) - (8/3).

To subtract fractions, we need to have a common denominator. In this case, the common denominator is 12.

(27/4) - (8/3) = (3 * 27 - 4 * 8)/12 = 55/12.

Therefore, the solution to the fourth expression is 55/12.

To summarize, the solutions to the given arithmetic expressions are: 1) 29/12 2) 13/6 3) 29/4 4) 55/12.
