The three place values in 324 are as follows:
3 = hundreds (100)
2 = tens (10)
4 = ones (1)
The four place values in 0.324 are as follows:
0 = ones (1)
3 = tenths (1/10)
2 = hundredths (1/100)
4 = thousandths (1/1000)
With this knowledge, we can see that the 2 in 324 is in the “tens” place. Meanwhile, the 2 in 0.324 is in the “hundredths” place.
I hope this answers your question!
