FRACTION SKILLS QUIZ

• WHAT U NEED 2 KNOW FOR THE TEST!

2
FRACTIONS !
After reviewing your notes working on our
class assignments, FOLLOW ALONG WITH this quiz to
get an idea whether you know your 'Fraction
Stuff'.
DIRECTIONS
Solve each problem on separate paper then ADVANCE
THE SLIDE TO SEE THE CORRECT ANSWER
3
Okay, here we go
Remember to try cross-canceling!
4
1 3
3 5
1 5
5
Compute the following
Seems to me there is something special we do with
whole numbers do you remember ???
6
First, we put the whole number over a 1.
Now cross-cancel !

Question 3

Start with rewriting the mixed number

9
Multiply this one . . .
10
Okay, we have 2 things to do here before we even
try to multiply.
We rewrite this whole numbers go over 1, mixed
numbers get changed to improper fractions.

11
Okay, the last multiplication problem
12
2 big rewrites to start this problem

15 2

13
Now its time for division !
14
Division Reciprocals !That means we FLIP!
Once we do the rewrite / flip,
its just another
multiplication problem

Question 7, have you remembered to write all of
your answers in lowest terms?
16
U should be getting use to this first step
REWRITE !

Compute the following

Rewrites and FLIP old news

Number 9
20
Rewrite . . .
With this example, we dont have any
cross-canceling
21
Almost done with the division
22
Lots of work to get this question ready to solve

34 63
1
It might look ugly but thats the answer cant
simplify this one any better.
23
Last division problem, Good Luck !
Yes this is a division problem so which number
do we flip ???
24
1 8
25
Number 12 time for some adding subtracting
questions !
26
First, put the fractions in columns then get
common denominators
Remember , we only add the numerators (top S)

------------------------
7 9
27
BASIC ADDITION, JUST LIKE THE LAST ONE.
REMEMBER, PUT THE FRACTIONS IN COLUMNS- ITS
EASIER TO SOLVE EM THIS WAY
28
Okay, the same set up as the last question

--------------------------
31 35
29
NOW LETS ADD MIXED NUMBERS !
30
With mixed numbers, we add whole S and then we
add fractions then we need to check our answer
to make sure its in lowest terms

----------------------------------

32
Some people get mixed up when they see a question
like this one . . . But these questions are
actually very simple!
Add the whole s Then Add the fractions . Oops,
there arent any fractions to add.

------------------------
3 4
25
33
Be careful . . . Make sure your answer is in
lowest terms !
34
U cant leave an improper fraction in your answer
------------------------
9 6
14
Now, put it all together and the answer is . . .
12
15
35
ENOUGH ADDING, HOW ABOUT SOME SUBTRACTION?
36
Same idea Same set up
1- put em in columns 2- get common
denominators 3- this time we subtract the
numerators
-------------------------
11 16
37
ILL GIVE YOU ONE MORE EASY ONE BEFORE WE MOVE ON
TO THE TOUGHER ONES!
38
Take your time and try to get the least common
denominator.
---------------------------
5 18
39
Now we should be ready for mixed numbers
40
Same idea as adding mixed numbers remember
those?
Subtract the fractions, and then subtract the
whole numbers.
13 24
11
41
Heres an easy one for you
42
No big deal, this one is just like the last one.
1 4
1
43
Once again, some folks have trouble with these
line up everything in columns first!
44
Dont make this one tougher than it is Subtract
the whole s and then just bring down the
fraction part!
---------------------

45
BE CAREFUL HERE . . .
46
Okay, here comes the borrowing questions !
Since u can not subtract 5/17 FROM NOTHING ABOVE
IT, U NEED TO BORROW
----------------------------------------------
12 17
When u borrow it looks like this
16
47
ANOTHER BORROW QUESTION, BUT JUST A LITTLE
DIFFERENT THAN THE LAST ONE
48
Follow the steps . . .
When u borrow from the 8, u get 7 and 6/6 but u
need to add the 6/6 to the 1/6 that was already
there ! Thats how we get 7 7/6
------------------------------------------
1 3

49
OKAY, LAST ONE !
50
Steps
1- line em up in columns 2- find common
denominators 3- borrow 4- subtract 5- check your
answer to make sure its in lowest terms
Do you think you have the right answer ???

The End !!
I hope this PowerPoint presentation has helped
you better understand fraction arithmetic.
Remember, the idea is for you to try these
problems before you click to the solution slide
that way you can check your understanding of the
concepts! MrB
