Nicole has two ribbons. The first ribbon measures 90 centimeters and the second string measures 75 centimeters. She wants to cut the ribbons into equal lengths so she'll have a bunch of smaller ribbons that are all the same length. What is the least number of ribbons of equal lengths that she can get? (Hint: The least number of smaller strings means each smaller piece is the largest it could possibly be.)
Each smaller ribbon will be 15 centimeters long. The 90 cm ribbon will be cut into 6 pieces that are 15 cm each. The 75 cm ribbon will be cut into 5 pieces that are 15 cm each. Together she will have 11 small pieces.
