Using usual order order of operations, which would it be?
Look at this.
i wasn't paying attention in class. i'm guessing for this one problem correct me if i'm wrong.
3/5/7 = 21/5
that may be confussing so in word form it's 3 over 5 over 7. to solve the the problem i multiplied the whole thing by 7 to cancel out the 7 on the bottom. that's the right answer right?
right?

But
As Plato said, "3/5/7" is bad notation as it is ambiguous. It could mean (3/5)/7 or 3/(5/7) and those are different.
(The basic arithmetic operations are defined on two numbers at a time. When we write "3+ 5+ 7" or "3*5*7" we could mean "(3+ 5)+7" or "3+(5+7)", "(3*5)*7" or "3*(5*7)". In the case of addition or products, those are the same so it doesn't matter. For the "inverse" operations, "3-5-7" or "3/5/7" that is not true. (3- 5)- 7 and 3- (5-7) are NOT the same, (3/5)/7 and 3/(5/7) are NOT the same.
(Technically, we say that addition and multiplication are "associative". Subtraction and division are not associative operations.)
