A wall of a building is 26 inches wide. Twelve inches is concrete, 10 inches is brick, and 44 inches is limestone. What fraction of the wall is concrete ?
To find the fraction of the wall that is concrete, we first need to find the total width of the wall.
Total width = concrete width + brick width + limestone width
Total width = 12 inches + 10 inches + 44 inches
Total width = 66 inches
Now, we can find the fraction of the wall that is concrete by dividing the concrete width by the total width of the wall.
Fraction of the wall that is concrete = concrete width / total width
Fraction of the wall that is concrete = 12 inches / 66 inches
Fraction of the wall that is concrete = 2 / 11
Therefore, the fraction of the wall that is concrete is 2/11.
