Answer:
Amelia has the most homework to complete. She has 12 questions left to go. Phoebe has only 9.
Explanation:
The easiest way to do this is to figure out the fractions represent how many questions are left.
Phoebe: 1 - 75/100 = 25/100 She has 25/100 left to go.
Emilia: 1 - 2/3 = 1/3 Emilia has 1/3 of the questions left.
Knowing that
Phoebe: 25/100 * 36 = 900/100 = 9. Phoebe has nine questions left.
Amelia: 1/3 * 36 = 12 Amilia has 12 questions left to go.
