4 2/21÷2 4/21=86/21*21/46=43/23=1 20/23.

Answer 2

Let's solve the given expressions one by one:

1. 3 ÷ (3/4): To divide by a fraction, we multiply by its reciprocal. 3 ÷ (3/4) = 3 × (4/3) = 4

2. (6/11) ÷ 2: To divide a fraction by a whole number, we multiply the fraction by the reciprocal of the whole number. (6/11) ÷ 2 = (6/11) × (1/2) = 6/22 = 3/11

3. 49 ÷ (7/11): Again, to divide by a fraction, we multiply by its reciprocal. 49 ÷ (7/11) = 49 × (11/7) = 7 × 11 = 77

4. (3 1/3) ÷ (10/27): First, convert the mixed number to an improper fraction. 3 1/3 = (3 × 3 + 1) / 3 = 10/3

Now, we can divide by the fraction using multiplication by its reciprocal. (10/3) ÷ (10/27) = (10/3) × (27/10) = 270/30 = 9

5. (4 2/21) ÷ 2: Convert the mixed number to an improper fraction. 4 2/21 = (4 × 21 + 2) / 21 = 86/21

Divide by 2 using multiplication by the reciprocal. (86/21) ÷ 2 = (86/21) × (1/2) = 86/42 = 43/21

So the solutions to the given expressions are:

1. 3 ÷ (3/4) = 4
2. (6/11) ÷ 2 = 3/11
3. 49 ÷ (7/11) = 77
4. (3 1/3) ÷ (10/27) = 9
5. (4 2/21) ÷ 2 = 43/21
