#2 is 3/4 > 3/8
algebra compare rational numbers - marko pls help, Wednesday, December 7, 2011 at 9:30pm
so all but #2 is wrong i see what i did now on # 2 and agree should be <
as:
-3/4 becomes -0.75
-3/8 becomes -0.375

so -0.75 < -0.375

right?

im really confused because i posted this question earlier and someone else just replied and said all my answers are wrong. so now im confused if im right or wrong?

From your above ....

opps sorry i did it again
it should be - 3/4 > -3/8

NO!

Your way, (the way your teacher showed you)
-3/4 = -.75
-3/8 = -.375

Now which is farthest to the right, that is the larger, so
-.375 > -.75 or -3/8 > -3/4

My way, the way I showed you in the other post

3/4 ....... 3/8
3/4 > 3/8
-3/4 < - 3/8
