Answer 1

2.5 or 2+1/2

Explanation:

2 (2/5) walls (x) = 6 rolls of paper (y), solve for x

12/5x = 6y

multiple both sides by 5 to clear your fraction

12x = 30y

now divide by 12 to leave x alone

x = 30/12y

now simplify your fraction with your greatest common denominator:

GCD = 6 so 30/12y becomes 5/2y

Convert to whole numbers:

5/2 = 2 + 1/2 or 5/2 = 2.5

so x = 2.5y

OR x (your walls) use 2.5 y (rolls of paper) each
