Answer:
7 to 3 is this answer
Step-by-step explanation:
if you noticed, with all the other ones they all have 3 : 7 in it. So by the process of elimination it's 7 to 3 that is different. I'll tell you why,
3 : 7, that is the ratio we have as an example. That's why it isn't the different one.
3 to 7, you say 3 : 7 as 3 to 7 to it still has the same ratio
3/7, this is how to type the fraction version of the ratio so it makes sense that it is the same one as 3 : 7.
7 to 3, if you haven't noticed yet, all of them has 3 : 7 as a counterpart. They are all the same but this one, this is 7 : 3 or 7 to 3. So with logic, this is the different ratio.
I think number 6 it should be right I think
Use PEMDAS. So it would then simplify to [100+(586+4)]/5<19 then continueing that it would be [100+590]/5<19 and then 690/5<19 which finally will be 138<19 and that is a valid statement
