7.5 ≤ 7.5
how about this ?
Is 7.5 less than or equal to 7.5 ?
OpenStudy (anonymous):
okay the ≤ what is that?
ganeshie8 (ganeshie8):
\(\le \) is read as "less than or equal to"
it means "at most"

Umm xD where did eriwan goooo?
ganeshie8 (ganeshie8):
\(7.5 \le 7.5\)
suppose your height is \(7.5\) and your brother height is also \(7.5\)
is it okay to say, you're "at most" as tall as your brother ?
OpenStudy (anonymous):
so its a choice i would say
ganeshie8 (ganeshie8):
Yes \(7.5\le 7.5\) is a true statement
so it has to be chosen
OpenStudy (anonymous):
Okay my next guess is the first one is correct!
