Class Notes 12/15

Today in class we covered sections 4-3 (greatest common factors) and 4-4 (decimals and fractions)

In the first section we learned that we can find the greatest common factor of 2 or more numbers by using a few different strategies. The first strategy that we can use is to list all factors of all numbers and then figure out the largest factor all the numbers have in common. The second strategy we can use it to use prime factorization using a factor tree and the last strategy involves prime factorization using the ladder method.

The second section focused on converting decimals into fractions and fractions into decimals.
