Explanation

A three-digit number has three digits: the first is hundreds, the middle is tens, the last is ones. 324 = 3 hundreds 2 tens 4 ones – “uch yuz yigirma to‘rt” (three hundred twenty-four). We can also say 32 tens and 4 ones.

Worked examples
5 hundreds 8 tens 3 ones = 583.
276 = 2 hundreds 7 tens 6 ones = 27 tens 6 ones.
