Intuition

Understand first, compress later.

Fractions, decimals and percentages are different representations of the same quantity idea.

Switch representations
Hundred square37 %
10 by 10 cells37 of 100 cells
one cell = one hundredth
shaded cellsempty cells
The square is cut into 100 equal cells — each cell is one hundredth, that is 1%. 37 cells are shaded: 3 complete rows of ten and 7 more.
Formal view

You can percent as hundredths when you can recognise the underlying objects, select valid rules and check each step for equivalence or logical implication.

Why does it work?

This skill sits on a prerequisite network. If a step is unstable, repair the missing prerequisite instead of merely doing more items of the same type.
