Answer: width = 2/15 miles
Explanation:
Area of a rectangle = l * w
In this case, our equation is 3/9 = 5/2 * w
What we need to do to find the width, is isolate the w variable.
To do so, the 5/2 is going to be divided by itself to get the variable w completely isolated.
With equations like this, whatever you do on one side, you do to the other. So, the area will also be divided by 5/2.
3/9 / 5/2 the common term "Keep, Change, Flip (KCF)" can be used to solve this.
You keep the first fraction as is, change the division sign to multiplication, and flip the second fraction to its reciprocal.
3 x 2 = 6
9 x 5 = 45
6/45 can be further reduced with the GCF of 3 resulting in your answer,
width = 2/15 miles
