I need to know 7 divided by 4/5 =
Basile [38]

Answer:

8.75 or 8 3/4

Step-by-step explanation:7

   

The numbers in 7 divided by 4/5 are labeled below:

7 = whole number

4 = numerator

5 = denominator

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 5

4

 =    

35

4

Thus, the answer to 7 divided by 4/5 in fraction form is:

35

4

To make the answer to 7 divided by 4/5 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:

35 / 4 = 8.75

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

35/4 is an improper fraction and should be written as 8 3/4.
