On the blueprint of Lauren’s new office building, the scale is 3 inches equals 8 ft. What will be the actual of Lauren’s office if it measures 6 inches long on the blueprint?

(3 in/8 ft) is your ratio. Top and bottom are the same, you just multiply by that or the inverse to make the units come out

you have 6 inches
so you multiply by (8 ft/3 in) to get ft

6 in (8 ft/3 in) = 16 ft
6 inches = 2 * 3 inches.

Multiply: 2 * 8 ft.
