Ratios!

Hey everyone! Here are the warm-up problems from today followed by the notes from the lesson on ratios. I hope this helps.

Sorry about the formatting on the warm-up problems. The multiplication and division signs look very strange. My handwriting shows what the problem should look like.

Lesson notes: 
Remember the first number shown is the numerator, and the second number is the denominator. DO NOT turn improper fractions into mix numbers... you lose the comparison of two numbers (ratio) that way!
