There are five tenths in the number 54.724. To find this, you look at the digit in the tenths place, which is 7. This digit represents seven tenths. The digits to the right of the tenths place do not contribute to the number of tenths.
Look at the hundredths place only. If it is 5 or more round up, add one to the tenths place, and throw away the hundredths and all decimal parts to the right of it.

Ex: 65.734 ... 3 is the hundredths place and is less than 5 ... round down = 65.7 or 74.38111 --- 8 is the hundredths place and is greater than 5 ... round up = 74.4
