"Express the rational number ​27 ​ ​19 ​​ as a terminating decimal or a decimal that eventually repeats. If necessary, include 6 digits to the right of the decimal point in your answer. Do not round. If this is a repeating decimal, enter in the part that repeats. If this is a terminating decimal, enter 0. (For example, for 1. ​031 ​​ you would enter 031, and for 1.57 you would enter 0.)" Really, really confusing inputs. At least it shows negative (non-repeating) cases.

ExpressAn ordering5
"Express the top number in scientific notation by dragging the decimal in the bottom number:" You drag the decimal point just before the last digit (for numbers > 1) and after the first digit (for numbers < 1). This definition of "scientific notation" conflicts with the last. Here three digits follow the decimal point. Earlier, there were no digits after the decimal point. This sets you up poorly for the next section where you have to write the notation from scratch.
