# Lesson 4

## Pizza, pie or both? This week’s lesson focuses mostly on operations with fractions.  Every time you eat pizza or have some delicious homemade pie, you are cutting it into fractional parts.  All of the parts add up to the whole pizza or the whole pie.  You will need to know how to add, subtract, multiply and divide fractions without a calculator.  The challenging part of this week’s lesson is doing conversions.  This would be converting miles per hour to kilometers per hour or converting dollars per pound to pesos per gram or converting feet per second to yards per hour.  Each of these conversion problems are set up as a fractions multiplication problem.  I recommend to first learn how to do operations with fractions, then work on the conversions.  You will need to budget extra time to learn to do the conversions correctly.
