Answer:
It will take him 5 nights to finish the essay.
Step-by-step explanation:
Given data:
Total pages 4
4/5 is written every night
Let the total number of nights be X
(4/5)X = 4
X = 4/(4/5)
X = 4 * 5/4 (invert the fraction )
X = 20/4
X = 5 nights
Answer: it will take 5 nights
Step-by-step explanation:
Total number of pages to be written is 4 pages
If he writes 4/5 page each night
Assume the number of night be n
: (4/5)n = 4
4n/5 = 4
4n = 4 * 5
4n= 20
n = 20/4
n = 5
It will take 5 night to finish the essay.
or
The remaining part of the essay on each day = 1/5
Therefore 1/5 *5 =5
It will take five nights to cover up for the remaining part of the pages left on each days.
