In order to better understand decimals and place values, let’s imagine that we have a cash register that only has bills and coins that are powers of .

LESSON

When we read decimals, we need to use our understanding of place values to identify the value of the whole part and the decimal part, which are separated by a decimal point.
millions
hundred-thousands
ten-thousands
thousands
hundreds
tens
ones
tenths
hundredths
thousandths
ten-thousandths
hundred-thousandths
millionths decimal point Think of the decimal point as separating dollar bills from coins. Just like we would read as dollars and cents, we split up the whole part and the decimal part of a number:
 Whole Part Decimal Point Decimal Part Number Numerical Expansion Expansion hundred tens ones tenths hundredths thousandths In Words one hundred fifty-six and two hundred thirty-eight thousandths
Notice that in words, we read the decimal part as the number with the farthest decimal place value name, in this case ⬆️, thousandths.
Now that we know our basics, let’s check out some examples of how to understand decimals!
