compare < > =
1)  1/7 6/7
i got : <
2) 3/4 3/8
i got: <
3)  1/2  2/10
i got : >
4)  3/4 1
i got: <
5)  1/2  5/6
i got: <
6) 4/5 1/3
i got: >
7) 5.2 > 8.3
8) 6.5 > 6.2
9) 4.9 > 4.3
10) 1.09 < 1.90
11) 1.22 < 6.5
12) 10.2 < 10.23
are these correct?

1)  1/7 6/7
i got : <  no, 1/7 is to the right of 6/7 on the number line
2) 3/4 3/8
i got: <  ✔
3)  1/2  2/10
i got : >  no, 1/2 is to the left of 2/10 , so it is smaller
4)  3/4 1
i got: <  no , 3/4 is to the right of 1
5)  1/2  5/6
i got: <  no
6) 4/5 1/3
i got: >  no
7) 5.2 > 8.3  ✔
8) 6.5 > 6.2  no
9) 4.9 > 4.3  no
10) 1.09 < 1.90 no
11) 1.22 < 6.5  no
12) 10.2 < 10.23  no
You seem to be missing the concept here
Have you drawn a number line ?
Comparing two positives should give you no problem, since you would say
larger > smaller
If one is +, the other negative, that is even easier, obvious
positive > negative in all cases
here is a neat method to make sure you get the 2 negative case correct
e.g. #11) 1.22 and 6.5
write them down as positives without any >or<
1.22 ..... 6.5
it should be easy to see which sign belongs, in this case the <
so 1.22 < 6.5
then  1.22 > 6.5 (notice I reversed the < sign to > )
try that method on those you missed and you will see why you were wrong. 
now here is the example from school notes:
 3/4 ad  1/2
compare < > =
3/4 becomes .75 and
 1/2 becomes .5
so 75 is < .5 is that right? 
reiny could you see what dana posted she said all but 1 was wrong im confused
no #2 was wrong it s/b > 
Yes, your last example is done correctly
It looks like your teacher wants you to change the fractions to decimals and the consider where they are on the number line
the .75 would be to left of .5 , so it is smaller and
.75 < .5
3/4 < 1/2
Notice you will get the same result if you do it my way.
You obviously did not follow your own example when you did all those questions 
im sorry i will redo this its getting confusing. your right im not really following i was out sick yesterday and will go in early tomorrow
im sorr
