Andy is hanging wallpaper in his kitchen. He is able to cover 2 2/5 of the walls in the room using 6 rolls of wallpaper. What is the number of rolls of paper used per wall?
The number of rolls per wall is _____.

Answer 1

To find the number of rolls of wallpaper used per wall, we need to divide the total number of rolls used by the total number of walls covered.

Given:
- Total rolls of wallpaper = 6 rolls
- Total walls covered = 2 2/5

First, we need to convert the mixed number 2 2/5 into an improper fraction.

2 2/5 = (2 * 5 + 2) / 5 = (10 + 2) / 5 = 12 / 5

Now, we can calculate the number of rolls per wall:

Number of rolls per wall = Total rolls / Total walls covered
Number of rolls per wall = 6 / (12/5)

To divide by a fraction, we multiply by the reciprocal:

Number of rolls per wall = 6 * (5/12) = (6 * 5) / 12 = 30 / 12

Now simplify the fraction:

30 / 12 = 5 / 2

Thus, the number of rolls of paper used per wall is:

5/2

So the final answer is:

5/2
