conversations.value: Can you provide an in-depth solution for: If Katherine has 4 apples and 3 times as many pears in her fridge, how many bananas does she have if she has a total of 21 pieces of fruit?Hey there, could you help me solve this math problem: If Katherine has 4 apples and 3 times as many pears in her fridge, how many bananas does she have if she has a total of 21 pieces of fruit?
conversations.from: assistant
conversations.value: Katherine has a total of 3 * 4 apples = 12 pears
  She therefore had 4 apples + 12 pears = 16 apples and pears
  We know she has 21 total pieces of fruit, so this means she must have 21 total - 16 = 5 bananas
