conversations.value: I'm stuck on this math problem: Gina had $400. She gave 1/4 of her money to her mom,  used 1/8  of her money to buy clothes,  gave 1/5 of her money to a charity,  and kept the remaining money. How much did Gina keep?
  Can you help?

conversations.value: Gina's mom received 1/4 x $400 = $100.
  She used 1/8 x $400 = $50 to buy clothes.
  She gave 1/5 x $400 = $80 to a charity.
  Thus, she spent a total of $100 + $50 + $80 = $230.
  Therefore, Gina kept $400 - $230 = $170.
