Final answer:
To convert 900 feet to units when 2 units equal 3 feet, set up a proportion and solve for 'x'. The result is 1350 units are equivalent to 900 feet.
Step-by-step explanation:
The student is asking about a conversion from units to feet. The given conversion rate is: 2 units equal 3 feet. To find out how many units are equivalent to 900 feet, we need to set up and solve a proportion.
Firstly, we write the known conversion as a fraction:
2 units = 3 feet
Then, we create a proportion. If 2 units equal 3 feet, we need to find how many units equal 900 feet. We'll call the number of units needed 'x':
2 units / 3 feet = x units / 900 feet
To solve for 'x', we cross-multiply and get:
- 2*x = 3*900
- x = (3*900) / 2
- x = 2700 / 2
- x = 1350 units
So, you would need 1350 units to equal 900 feet.
