Question

Tiffany has a fancy ribbon of length 40 units. She wants to use the entire length of the ribbon to make tiny bows. She can make bows with ribbon pieces of length 3, 5, 6 and 7 units. Which lengths can she choose to make bows of the same size?

• A. 5

Answer 1

The correct option is A 5
We need to divide 40 units of length equally such that each length is 3, 5, 6 or 7 units.
Factors of 40: 1, 2, 4, 5, 8, and so on
Hence, the ribbon is cut into equal pieces of length 5 units each piece will be of equal length.
