Final answer:
To convert 3' - 9" to decimal form, we need to convert the feet to inches and add it to the given inches. Then, we divide the total inches by 12 to get the decimal form in feet.
Step-by-step explanation:
To convert 3' - 9" to decimal form, we need to convert the feet to inches and then add it to the given inches. Since 1 foot is equal to 12 inches, we have 3 feet as 3*12 = 36 inches. Adding the given 9 inches, we have a total of 36 + 9 = 45 inches. Now, to convert this to decimal form, we divide by 12 (since there are 12 inches in a foot). Therefore, 45 inches is equal to 45/12 = 3.75 feet in decimal form.
