Final answer:
The longest length Alexis can cut the ribbons is 10 centimeters, and she will have a total of 11 pieces of ribbon.
Explanation:
To find the longest length that Alexis can cut the ribbons, we need to find the greatest common divisor (GCD) of the lengths of the ribbons. The GCD of 40 and 70 is 10. Therefore, the longest length she can cut the ribbons is 10 centimeters.
To determine the number of pieces of ribbon she will have in total, we divide the length of each ribbon by the longest length. For the first ribbon, 40 divided by 10 is 4, and for the second ribbon, 70 divided by 10 is 7. So in total, Alexis will have 4 pieces from the first ribbon and 7 pieces from the second ribbon, giving her a total of 11 pieces of ribbon.
