An exact spot between two whole numbers

A line from 5 to 6 has ten equal gaps. Where is 5.3 on that line?

The rule

Count three gaps from 5. That is where 5.3 is.

A decimal with parts lies between two whole numbers. The lower one is its whole part. 5.3 is between 5 and 6.

Each gap is a tenth. Three tenths past 5 is 5.3.

Cut each gap into ten parts for hundredths. 1.06 is six hundredths past 1.

2.4 and 2.40 are the same point. No hundredths is the same as zero hundredths.
