Beginning with Whole Numbers

Is there a difference between having 70 dollars and having 7 million dollars? Of course. That is the importance of place value.

Place value is the position of a single digit in the number. The position of a number is how far from the right or left it is from the decimal point. (If there is no decimal point, it is assumed to be at the end of the number.)

For example, in the number 70, the 7 is two places from the right.

In the number 7,000,000, the 7 is seven places from the right.

The first place to the right of the decimal is the ones place. The next one to the right is the tens place. The third place from the right is the hundreds place.

In a whole number, the value of each place is 10 times greater than the place to the right. Places to the left have a much larger value.

More Whole Numbers

For numbers larger than 3 digits, we use commas to separate the places. A comma should be placed every 3 places to the left of the decimal. (Make sure to count from right to left when placing commas.) Each set of three digits is called a period.

To figure out where the comma goes, start counting from the decimal place or the number most to the right if there is no decimal place, after each set of three numbers, write a comma.

Now, let’s look at place value for larger numbers.

We’ve already learned that the first place to the right is the ones place. The next one to the right is the tens place. The third place from the right is the hundreds place.

The next period is called the thousands. The fourth place to the left is the thousands. The fifth place to the left is the ten thousands. The sixth place to the left is the hundred thousands.

The next period is called the millions. The seventh place to the left is the millions. The eighth place to the left is the ten millions. The ninth place to the left is the hundred millions.

Knowing these place names is important in knowing how to read a number.

1,986,000 is read “one million nine hundred eighty six thousand.”

549,119 is read “five hundred forty nine thousand one hundred nineteen.”

10,540,455 is read “ten million five hundred forty thousand four hundred fifty five.”

6,056,123 is read “six million fifty six thousand one hundred twenty three.” (Note that a zero is in the hundred thousands place. This holds that place since there are no hundred thousands.)

Remembering the periods will help you know how to read numbers.

Decimal Numbers

Just as there are place values in whole numbers, there are also place values to the right of the decimal point.

The decimal point is a dot or period in a number that separates the whole number part of the number from the fraction part of a number. The part to the right of the decimal point shows a part of a whole number.

The digits in a decimal have different place values. Moving to the right of the decimal point, each decimal place value is 10 times smaller than the one to the left.

Remember that there is always a “th” in the name of decimal place values.

No commas are included in digits to the right of the decimal point.

The decimal .87 is read “eight seven hundredths” or “point eight seven.”

Decimals can also be written as fractions. The digits to the right of the decimal point go on top of the fraction (without the decimal point). The place value goes on the bottom of the fraction.

For example, if there is only one digit in the decimal (place value of tenths), 10 goes on the bottom of the fraction. If there are two digits in the decimal (place value of hundredths), 100 goes on the bottom of the fraction. If there are three digits in the decimal (place value of thousandths), 1000 goes on the bottom of the fraction.

When we count or compute amounts of money, decimals are important. The digits to the right of the decimal point are cents. The cents represent fractions of a dollar.

An amount of $234.55 means 234 dollars and 55 cents. The 55 cents is a part of a dollar.

Note that when stating an amount of cents, we don't write the decimal point. A dime is worth $.10 or 10 cents (not .10 cents).
