2. ответ: 3,75.
3. ответ: 3/5.

Answer 2

5 7/19-4 16/19=10/19; 9 5/16-5 9/16=3 3/4; 8 8/25-7 18/25=3/5

Answer 3

To solve these arithmetic problems involving fractions, we need to first find a common denominator for each pair of fractions in each equation.

1. 5целых7/19 - 4ц16\19

The common denominator for 19 and 16 is 304. So, we have:

5целых7/19 = (5 * 304 + 7)/304 = 1527/304 4ц16\19 = (4 * 304 + 16)/304 = 1224/304

Subtracting the second fraction from the first, we get:

1527/304 - 1224/304 = 303/304

Therefore, the solution to the first equation is 303/304.

2. 9ц5\16-5ц9\16

The common denominator for 16 and 16 is 16. So, we have:

9ц5\16 = (9 * 1 + 5)/16 = 149/16 5ц9\16 = (5 * 1 + 9)/16 = 89/16

Subtracting the second fraction from the first, we get:

149/16 - 89/16 = 60/16 = 15/4

Therefore, the solution to the second equation is 15/4.

3. 8ц8\25-7ц18\25

The common denominator for 25 and 25 is 25. So, we have:

8ц8\25 = (8 * 1 + 8)/25 = 216/25 7ц18\25 = (7 * 1 + 18)/25 = 193/25

Subtracting the second fraction from the first, we get:

216/25 - 193/25 = 23/25

Therefore, the solution to the third equation is 23/25.
