Question

solve. On an architect's blueprint, 1 inch corresponds to 6 feet. Find the length of a wall represented by a line 7 1/3 inches long on the blueprint. Round to the nearest tenth if necessary.

Answer 1

1 inch / 6 feet = 7 1/3 inches / x feet

Solve for x:

1/6 = 7 1/3 / x

First, express the mixed number as a simple fraction:

7 1/3 = (7x3 +1) / 3 = 22/3

1/6 = (22/3) / x

x = (22/3) 6

x = 44 feet
