Final answer:
The total length of the ribbons that Mabel cuts, which were each 7 centimeters long and she has 9 such pieces, is 63 centimeters.
Explanation:
The question involves the multiplication of two numbers, which is a mathematical operation. We're told that Mabel cuts 9 pieces of ribbon, each of which is 7 centimeters long. To find the total length of all pieces of ribbon, we need to multiply the number of pieces (9) by the length of each piece (7 cm).
So, the calculation would be: 9 pieces * 7 cm/piece = 63 cm
Hence, the total length of the pieces of ribbon that Mabel cuts is 63 centimeters.
