If Lauren and Jon bought 50 acres how many Hectares did they buy if 1 acre = .405 Hectares?

20.25 Hectares

Using the above question and answer how many square miles is their land if 1 mi^2 = 640 acres?

How would I set this part up

50/640 = x/1

640x = 50

x = 0.0312 square miles

How did you get x?

This reads as

50 acres is to 640 acres as unknown is to 1 square mile.

X = unknown.

640x = 50

Divide both sides by 640.

To determine how many square miles their land is, you can use the conversion factor that 1 square mile is equal to 640 acres.

Given that Lauren and Jon bought 50 acres, we can first calculate how many square miles this corresponds to.

Step 1: Convert acres to square miles:
To convert acres to square miles, divide the number of acres by the conversion factor of 640 acres per square mile.

In this case, divide 50 acres by 640 acres per square mile:

50 acres / 640 acres per square mile = 0.078125 square miles (rounded to 6 decimal places)

So, Lauren and Jon's land is approximately 0.078125 square miles.
