Splinter wrote a three-digit number on the board. Then he asked each of the four Teenage Mutant Ninja Turtles (Leonardo, Raphael, Donatello, and Michelangelo) to count the number of letter in his name. (Donatello has 9 letters in his name.)
Splinter said that for each turtle, the number of the board minus the number of letters in the turtle's name is evenly divisible by the number of letters.
Each turtle confirmed that Splinter was right.

If kn = 9 cm, mn = 21 cm, rs = 42 cm, and ps = 18 cm, what is the scale factor of figure klmn to figure pqrs?

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. kevin spins the spinner 180 times. kevin determines about how many times the spinner will land on red or green, and his work is shown below. -kevin has the formula reversed; it should be the total number of sections over the number of red or green sections. -kevin should have used a 4 in the numerator because there are 2 red sections and 2 green sections. -kevin should multiply by the number of sections in the spinner rather than the total number of spins. -kevin calculated the prediction correctly and did not make any mistakes.
