What is the decimal place name for 3 in 423

The decimal place is called the ones place

Hello There!

Let me use an example number:
1'652'374.98
The 1 is the millions place
The 6 is in the hundred thousands place
The 5 is in the tens thousand place
The 2 is in the thousands place
The 3 is in the hundreds place
The 7 is in the tens place
The 4 is in the units place
The 9 is in the tenths place
The 8 is in the hundredths place.

In this case, the 3 is in the units or 'ones' place.

Hope This Helps You!
Good Luck :)
