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?

**Reiny**, Wednesday, December 7, 2011 at 9:21pm1) - 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.

**marko pls help**, Wednesday, December 7, 2011 at 9:27pmnow 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?

no #2 was wrong it s/b >

**Reiny**, Wednesday, December 7, 2011 at 9:37pmYes, 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
