#### Answer

$\frac{120}{150}=\frac{8}{10}$

#### Work Step by Step

We are given that 120 ft is to 150 ft as 8 ft is to 10 ft. In order to write this as a proportion, we can write both relations as fractions.
120 ft is to 150 ft can be written as $\frac{120 ft}{150 ft}$
8 ft is to 10 ft can be written as $\frac{8 ft}{10 ft}$
Next, we can set both fractions equal to each other, which gives us a proportional relationship.
$\frac{120 ft}{150 ft}=\frac{8 ft}{10 ft}$
Since the units in the numerators and denominators are same, we can simplify by dropping the units from both fractions.
$\frac{120}{150}=\frac{8}{10}$
