X/-5 +1 (is less than or equal to) 7
I can't paste the less than or equal to sign but it's < with a line underneath
You do --12/15---you see that this can be simplified by the same factor 3-- si you divide by 3 on both numbers thus you get---4/5 as the answer
Q: What is the value of the upper quartile?
A: C 9
Hope this helps!!!
