Answer part A and Part B

first one is 20 and second is 21

Step-by-step explanation:

7/(1/3)

To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:

7 x 3 1

  =    

21 1

Thus, the answer to 7 divided by 1/3 in fraction form is:

21 1

To make the answer to 7 divided by 1/3 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:

21 / 1 = 21

The answer is rounded to the nearest two decimal points if necessary.

21/1 is an improper fraction and should be written as 21.

for the

now the first one 4/(1/5) is 20 becaue...

To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:

4 x 5 1

  =    

20 1

Thus, the answer to 4 divided by 1/5 in fraction form is:

20 1

To make the answer to 4 divided by 1/5 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:

20 / 1 = 20

The answer is rounded to the nearest two decimal points if necessary.

20/1 is an improper fraction and should be written as 20.
