5.923 which is thousandths place

The 3. I think of it like this: Look at the decimals. There are 3 digits right? Well, there are three digits, so there are 3 zeros. So, its the thousandths place. Make sure you add ths at the end of places because they are decimals, not whole numbers.

Well 5 is ones

9 is tenths

2 is hundredths

3 is thousandths

so 3 is the answer
