Final answer:
To write the given ratio as a decimal, convert feet to inches and divide the two numbers to find the decimal value.
Step-by-step explanation:
To write the given ratio as a decimal, we need to convert either the feet or the inches into the same unit. Since there are 12 inches in a foot, we can convert 5 feet to inches by multiplying it by 12. So, 5 feet is equal to 60 inches. Now, the ratio becomes 60 inches to 55 inches.
To express this ratio as a decimal, we divide the first number (60) by the second number (55):
60 ÷ 55 = 1.0909...
Therefore, the ratio 5 feet to 55 inches can be written as 1.0909... when expressed as a decimal per one.
