Final answer:
To determine the number of towels that will fit each row along the back of the shower, divide the length of the back of the shower by the length of each towel.
Step-by-step explanation:
To determine the number of towels that will fit each row along the back of the shower, we need to divide the length of the back of the shower by the length of each towel. In this case, the back of the shower measures 6 feet long and each towel is 2/3 of a foot long. We can use the equation:
Number of towels = Length of back of shower / Length of each towel
Substituting in the given values, we have:
Number of towels = 6 feet / 2/3 feet = 6 feet * 3/2 feet = 9 towels
