if 1 inch equals 10 feet, than how many inches is 13 feet?
1.3
To solve this problem, we can set up a proportion using the given information that 1 inch equals 10 feet.
Let's assign a variable to represent the unknown number of inches. Let's call it "x".
The proportion can be set up as follows:
1 inch / 10 feet = x inches / 13 feet
To find the value of x, we can cross-multiply and solve for x:
1 * 13 = 10 * x
13 = 10x
Divide both sides of the equation by 10:
13 / 10 = x
x = 1.3
Therefore, 13 feet is equivalent to 1.3 inches.
