Which periods are shown in the place value chart at the right? ›

Starting from the right, the first column on a place value chart with no decimal point is the ones place, followed by the tens place, hundreds place, thousands place, ten thousands place, hundred thousands place and extending up to the billions place or beyond.

10 ones = 1 tens.

For example, we can write 163 as 1 hundred + 6 tens + 3 ones.

Third: 1/3, pronounced as "one-third." Quarter or Fourth: 1/4, pronounced as "one quarter" or "one-fourth". Fifth: 1/5, pronounced as "one-fifth."

There are 21 ones between 1 and 100 including 100. The general method of calculating : for 1 to 1,000,000,000 is : 1 one from 1 to 10 - 11, 1 to 100 - 21, 1 to 1,000 - 301, 1 to 10,000 = 4,001 etc.

Just as bundling 10 ones created 1 ten, bundling 10 tens creates 1 hundred (100).
