A machine can produce 27 inches of ribbon every 3 minutes. How many feet of ribbon can the machine make in one hour? Explain.

60/3 = x/27

Multiply both sides by 27, then divide by 3.

540

27 inches of ribbon is needed to wrap a present. How many presents can be wrapped in 12yards of ribbon

To find out how many feet of ribbon the machine can make in one hour, we need to convert the units from inches to feet and minutes to hours.

First, let's convert inches to feet. There are 12 inches in one foot. So, to convert from inches to feet, we divide the number of inches by 12.

In this case, the machine can produce 27 inches of ribbon in 3 minutes. Therefore, the machine can produce (27 / 12) = 2.25 feet of ribbon in 3 minutes.

Next, let's convert minutes to hours. Since there are 60 minutes in one hour, we can divide the number of minutes by 60 to get the equivalent value in hours.

In this case, the machine can produce 2.25 feet of ribbon in 3 minutes. So, to find out how many feet of ribbon the machine can make in one hour, we need to multiply 2.25 by (60 / 3) since there are 60 minutes in one hour.

Multiplying 2.25 by (60 / 3) gives us:
2.25 * (60 / 3) = 45 feet of ribbon

Therefore, the machine can produce 45 feet of ribbon in one hour.
