A classroom table is 1 meter wide and 1.75 meters long. How many 39 centimeter chairs can fit around the table?

One meter = 100 centimeters. Divide 100 by 39 to find how many chairs will fit along the 1-meter wide side. Multiply by 2.

1.75 meters = 175 centimeters. Divide by 39 and multiply the answer by 2.

To find out how many 39 centimeter chairs can fit around the table, we need to calculate the perimeter of the table and then divide it by the width of each chair.

First, let's calculate the perimeter of the table:
Perimeter = 2 * (Width + Length)

Given that the width of the table is 1 meter and the length is 1.75 meters:
Perimeter = 2 * (1 meter + 1.75 meters)
Perimeter = 2 * 2.75 meters
Perimeter = 5.5 meters

Now, let's convert the perimeter to centimeters:
1 meter = 100 centimeters
5.5 meters = 5.5 * 100 centimeters
5.5 meters = 550 centimeters

Finally, let's divide the perimeter of the table by the width of each chair to determine the number of chairs that can fit around the table:
Number of chairs = Perimeter / Width of each chair

Given that the width of each chair is 39 centimeters:
Number of chairs = 550 centimeters / 39 centimeters
Number of chairs ≈ 14.1

Since we can't have a fraction of a chair, the maximum number of 39 centimeter chairs that can fit around the table is 14.
