My Learning

During this unit I found That in order to find the lowest common denominator when adding and subtracting fractions, using the tree method will help you to fix any mistakes and get the right answer. First, to start the Tree method I take the 3 fractions denominator’s, (12,4,8) and break them apart into their prime factors. (for twelve that is 3,2,2 for eight 2,2,2 and four 2,2) I will then rewrite it as shown below. as well as how to break the numbers down.

I will then choose the greatest option for each number. in this case it is the two cubed and the three I would then multiply them together to get the lowest common multiple of twelve, eight, and four, which is twenty-four.

I was surprised by on the test

on the test for this unit one thing that surprised me was that there were multiple choice questions on a math test. The other was that the questions were easier than I thought they would be.
