### 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?

1. Good Job! you put effort into this and it shows but you should add pictures and videos.

2. Good Job ! Your pictures are nice. Next time you should add pictures/diagrams and show how you got the answer.

3. Good job Nikita! I like how you showed your work as to how you got your answers. Next time, you can improve by adding pictorial representations.
