Answer 2

Ответ:

5 2/3, 3 3/4, 15

Пошаговое объяснение:

1) 1 : 3/17 = 1/1 : 3/17 =1*17/1*3 = 17/3 = 5*3+2/3 = 5 2/3:

2) 11 2/3 : 3 1/9 = 11*3+2/3 : 3*9+1/9 = 35/3 : 28/9 = 35*9/3*28 = 315/84 = 15*21/4*21 = 15/4 = 3*4+3/4 = 3 3/4:

3) 5 5/6 : 7/18 = 5*6+5/6 : 7/18 = 35/6 : 7/18 = 35*18/6*7 = 630/42 = 15*42/1*42 = 15/1 = 15:

Answer 3

Let's calculate the expressions one by one:

1. 1 ÷ (3/1711):

To divide by a fraction, we multiply by its reciprocal. So, we can rewrite the expression as follows:

1 ÷ (3/1711) = 1 × (1711/3) = 1711/3 ≈ 570.333

2. (2/3) ÷ 3:

To divide by a whole number, we can multiply by its reciprocal. So, we can rewrite the expression as follows:

(2/3) ÷ 3 = (2/3) × (1/3) = 2/9 ≈ 0.222

3. 1/95:

This expression does not involve division, so it remains the same:

1/95 ≈ 0.0105263

4. (5/6) ÷ (7/18):

To divide by a fraction, we multiply by its reciprocal. So, we can rewrite the expression as follows:

(5/6) ÷ (7/18) = (5/6) × (18/7) = 15/7 ≈ 2.143

Therefore, the results of the expressions are:

1. 1 ÷ (3/1711) ≈ 570.333
2. (2/3) ÷ 3 ≈ 0.222
3. 1/95 ≈ 0.0105263
4. (5/6) ÷ (7/18) ≈ 2.143
