Using a place value chart, place a ones disk in the ones column. Now drag the ones disk to the tenths column to its right. Notice that each tenth is 1/10 of a one. Numbers with digits in place values smaller than the ones place are called decimals. Drag a tenth to the hundredths place to see that 1 hundredth is 1/10 of a tenth (or 1/100 of a one). Delete 1 hundredths disk. The count shows the decimal 0.99 because there are 0 ones, 9 tenths, and 9 hundredths.
