let's take a peek if that's so.
27 ÷ 3 = 9
27 ÷ 3 ÷ 9 => 9 ÷ 9 = 1
let's now change the order
9 ÷ 3 ÷ 27
9 ÷ 3 = 3, so 9 ÷ 3 ÷ 27 is 3 ÷ 27 = 0.1111111111111....
low and behold, we changed them about, and notice the different quotient.
recall, by order of operations, divisions are done from left-to-right.
