Q. 3. On a recent math test, Aubrey was asked to find the LCD of and and then to write equivalent fractions using this LCD. Aubrey felt confident that she answered the question correctly, but when she received her graded test, her answer was marked as incorrect. View
Aubrey's work below to find her mistake and then describe to Aubrey the mistake you found.
Aubrey's work:
Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24
Multiples of 4: 4, 8, 12, 16, 20, 24
LCD of 3 and 4 is 24. Equivalent fractions with the LCD: and

Asays "we are both knaves" and b says nothing. exercises 24–31 relate to inhabitants of an island on which there are three kinds of people: knights who always tell the truth, knaves who always lie, and spies (called normals by smullyan [sm78]) who can either lie or tell the truth. you encounter three people, a, b, and c. you know one of these people is a knight, one is a knave, and one is a spy. each of the three people knows the type of person each of other two is. for each of these situations, if possible, determine whether there is a unique solution and determine who the knave, knight, and spy are. when there is no unique solution, list all possible solutions or state that there are no solutions. 24. a says "c is the knave," b says, "a is the knight," and c says "i am the spy."
