Why do I need to know this stuff?

• Fractions can and will help you in real life. In
  order to figure out how to make only part of a
  recipe because you do not want to feed ten
  people, but only five, fractions will be very
  helpful.
• You can use fractions to divide cake, or candy,
  and you will need fractions to help figure out
  percents.
• Fractions are useful when you buy paint to make
  your house look nice and for figuring how much
  interest you will pay to the bank when you take a
  loan.
• Fractions may be a bit difficult to learn, but
  believe me, you will be happy that you spent the
  time.
