Nikita`s Fraction Scribepost

Question`s 1,4 and 9 in the textbook.

1) Anna divided 5/6 by 1/2 and stated that the quotient is 5/12.
        a) What was Anna`s mistake?
        b) What is the correct quotient. Use a diagram to show how you know.

 a) She did it wrong because she had multiplied the 5 by the 1 and the 6 by the 2 instead of doing the reciprocals

b) 5 x 2 = 10
     6    1     6
-----------------
    1 x 2
    2    1

  4) a) Does 2 1/2 divided by 1 1/2 equal 1 1/2 divided by 2 1/2?
b) if the quotients an part a) are not equal, how are they related
2 1/2 and 1 1/2 are improper so you have to make them proper fractions.
So 2 1/2 = 5/2 AND 1 1/2 = 3/2
Those are the proper fractions.
so you go 5/2 DIVIDED by 3/2 and you multiply 3/2 by 2/3 because you need to make a reciprocal.
and what you do to that side you also multiply 5/2 x 2/3 = 10/6 OR 1 2/3


           9) Divide.
                 a) 3
                     4



        b) 1 2/3 divided by 2 5/6








       c)  12 divided by 3/4



  










My Test Corrections
# 2. 1/4 + 5/8

2/8 + 5/8 = 7/8

#9. (the first question with the chart.)
5/6 x 1/2 = 5/12 
the question for that equation is What is 1/2 of 5/6?
