What is a decimal as a eighth note
Vera_Pavlovna [14]

Idk,
Tips with decimals....

Our decimal system gives us the flexibility to write numbers as large or small as we like. The key to the decimal system is the decimal point. Anything on the left of the decimal point represents a whole number, anything on the right of the decimal represents less than one (similar to a fraction). Going from left to right, the value of each place on the right of the decimal point is 1/10 the value of the place on the left. Good luck!
