What is the scale factor of 30 inches to 7 feet

Scale Factor = (7*12)in / 30 in = 2.8/1.

or 1:2.8. So to find the actual size, multiply the given size by 2.8.

To determine the scale factor between 30 inches and 7 feet, we need to convert the 7 feet measurement to inches since the two measurements should be in the same units.

Since 1 foot = 12 inches, the conversion factor from feet to inches is 12. Therefore, we can convert the 7 feet to inches by multiplying it by 12:
7 feet * 12 inches/foot = 84 inches.

Now that both measurements are in inches, we can calculate the scale factor between 30 inches and 84 inches:
Scale factor = 84 inches / 30 inches = 2.8.

Therefore, the scale factor of 30 inches to 7 feet is 2.8.

To determine the scale factor between 30 inches and 7 feet, we need to convert both measurements to the same unit. In this case, let's convert everything to inches.

First, we know that there are 12 inches in 1 foot. So, to convert 7 feet to inches, we multiply 7 by 12:

7 feet * 12 inches/foot = 84 inches.

Now that both measurements are in inches, we can find the scale factor by dividing the larger measurement by the smaller measurement:

Scale factor = larger measurement / smaller measurement

Scale factor = 84 inches / 30 inches

Simplifying this fraction, we get:

Scale factor = 2.8

Therefore, the scale factor of 30 inches to 7 feet is 2.8.
