Vicky's Scribe Post

On January 11, 2008 Mr. Harbeck gave my class a fraction test. There were 6 questions on the test, and he ask me to do a scribe post on question 3 and 4.Question # 3 was 5 9/10 - 2 1/10First I subtract the whole numbers. 3 - 5 = 2.Then I used common denominator 9/10 x 1 = 9/10, 4/5 x 2 = 8/10 Next I subtract the two common denominator fractions. 9/10 - 8/10 = 1/10Then I add 1/10 to 2, and i got my answer2 1/10.Question # 4 was 5 2/5 - 3 13/20First I subtract the whole numbers. 3 - 5 = 2.

Then I used common denominator

2/5 x 4 = 8/20, 13/20 x 1 = 13/20

Next I subtract the two common denominator8/20 - 13/20 = 5/20

After that I simplify 5/20

5/20 ÷ 5 = 1/4Then I add 1/4 to 2, and i got my answer 2 1/4.
