conversations.value: I need help with this problem:
  Ali and Sara ate 80 small apples combined. Ali ate 4 times more apples than Sara. How many apples did Sara eat?
conversations.from: assistant
conversations.value: Let A be the number of apples Ali ate and S be the number of apples Sara ate.
  We have: A + S = 80 apples
  And: A = 4S
  Which means: 4S + S = 80
  So: 5S = 80
  So the number of apples Sara ate is: S = 80 / 5= 16 apples
