My question is: Heidi's apartment has 3 times as many rooms as Danielle's apartment. Grant's apartment has 1/9 as many rooms as Heidi's apartment. If Grant's apartment has 2 rooms, how many rooms does Danielle's apartment have? Your thoughts:
Heidi's apartment has 2 * 9 = 18 rooms. Danielle's apartment has 18 / 3 = 6 rooms. The final answer: 6.
