Answer:


1. \: \: \: (5)/(3) \\


2. \: \: (4)/(1) = 4 \\


3. \: \: (1)/(1) = 1 \\


4. \: \: 3 / (3)/(4) \\ = 3 * (4)/(3) \\ = 4 \\


5. \: \: 5 / (3)/(4) \\ = 5 * (4)/(3) \\ = (20)/(3) \\ = 5 (5)/(3) \\


6. \: \: 8 / (4)/(7) \\ = 8 * (7)/(4) \\ = 14 \\


7. \: \: 6 / (3)/(5) \\ = 6 * (5)/(3) \\ = 10 \\


8. \: \: 2 / (5)/(8) \\ = 2 * (8)/(5) \\ = (16)/(5) \\ = 3 (1)/(5) \\


9. \: \: 4 / (8)/(9) \\ = 4 * (9)/(8) \\ = (9)/(2) \\ = 4 (1)/(2) \\

When finding the reciprocal, it is basicaly flipping the numerator and denominator of the number. For instance, the reciporcal of 2 is 1/2, because the denominator of 2 would be 1. For an example more straight forward, the reciporacle of 3/5 is 5/3. This applied to the question goes as followed.

1. 3/5 is 5/3

2. 1/4 is 4

3. 1 is 1

Similarly when dividing fractions or an integer to a fraction, the fraction that is dividing the number turns into the reciprocal then you would multiply.

4. 3/(3/4) is 3*4/3= 4

5. 5/(3/4) is 5*(4/3)= 20/3

6. 8/(4/7) is 8*(7/3)= 56/3

7. 6/(3/5) is 6*(5/3)= 10

8. 2/(5/8) is 2*(8/5)= 16/5

9. 4/(8/9) is 4*(9/8)= 9/2
