12) -10.2 < -10.23

are these correct?

Answer 1

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.

Answer 2

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?

Answer 3

reiny could you see what dana posted she said all but 1 was wrong im confused
no #2 was wrong it s/b >

Answer 4

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
