Question

Can someone help me please???

Answer 1

Let's start out with the general rule for simplifying fractions:

-- To simplify a fraction, look for a number that goes into
the numerator and denominator (a common factor). 

-- If you find one bigger than ' 1 ', then divide the numerator
and the denominator by it. 

-- Then try it again. 

-- When you don't find any common factor except ' 1 ',
then the fraction is in simplest form.

On your Practice 9-2 sheet:

#1).  5/10
' 5 ' can go into both the numerator and the denominator,
so divide them both by it.  Then you have  1/2 .

#4).  3/15
' 3 ' can go into both the numerator and the denominator,
so divide them both by it.  Then you have  1/5 .

#7).  2/18
' 2 ' can go into both the numerator and the denominator,
so divide them both by it.  Then you have  1/9 .

#8).  25/60
' 5 ' can go into both the numerator and the denominator,
so divide them both by it.  Then you have  5/12 .

#9).  12/72
' 2 ' can go into both the numerator and the denominator,
so divide them both by it.  Then you have  6/36 .

That's not the simplest form yet.  ' 2 ' can go into both the
numerator and the denominator again, so divide them both by it. 
Then you have  3/18 .

That's STILL not the simplest form.  ' 3 ' can still go into both the
numerator and the denominator, so divide them both by it. 
Then you have  1/6 .  That's the simplest form.

#11).  The fraction of the test that will be word problems is

         (the number of word problems)
divided by
         (the total number of questions on the test) .

The total number of problems on the test is (20 + 10 + 5) = 35 .

So the word problems will be  5/35  of the test.
Simplify that.

Do EVERYTHING on this sheet the same way.  This sheet is
nothing but 14 different problems in simplifying fractions.
