Samantha makes hair barrettes from ribbon. She has 3 1/4 ft of ribbon and uses 1/2 ft of ribbon to make each barrette. How many completed barrettes can Samantha make with the ribbon she has.

Answer: she can only make 6 completed barrettes

Step-by-step explanation:

Samantha makes hair barrettes from ribbon. The total length of ribbon that she has is 3 1/4 feet. Converting 3 1/4 feet to improper fraction, it becomes 13/4 feet.

She uses 1/2 feet of ribbon to make each barrette. This means that the number of completed barrettes that Samantha can make with the ribbon she has would be

(13/4) / (1/2) = 13/4 * 2/1

= 6 1/2 barrettes

The complete barrette must be whole number.

Therefore, she can only make 6 completed barrettes
