What is a decimal place value in expanded form?

A decimal place value in expanded form breaks down a decimal number into its individual place values, such as tenths, hundredths, thousandths, etc. For example, the decimal number 3.456 in expanded form would be: 3 + 4/10 + 5/100 + 6/1000.

How do you write the value of the decimal place in expanded form?

To write the value of a decimal place in expanded form, you can express the decimal number as the sum of each digit multiplied by its respective place value. For example, in the number 4.56, the "4" is in the tens place, so its value is 4 * 10 = 40. The "5" is in the tenths place, so its value is 5 * 0.1 = 0.5. Finally, the "6" is in the hundredths place, so its value is 6 * 0.01 = 0.06. Thus, the expanded form of 4.56 would be 40 + 0.5 + 0.06.

What is the purpose of using expanded form for decimal place value?

The purpose of using expanded form for decimal place value is to break down a decimal number into its individual place values in order to better understand and visualize the value of each digit. This can help with performing mental math operations, comparing numbers, and interpreting the value of a decimal in terms of its place value positions.

How do you represent the tenths place in expanded form?

To represent the tenths place in expanded form, you would write the decimal number with the tenths place value as a sum of fractions or as a product of powers of 10, such as in the form of (1/10) x ??.

What is the expanded form of a decimal number with three decimal places?

The expanded form of a decimal number with three decimal places would present the value of each digit taking into account its position in relation to the decimal point. For example, the decimal number 3.456 would have an expanded form of 3 + 0.4 + 0.05 + 0.006.

How do you express the hundredths place in expanded form?

To express the hundredths place in expanded form, you would write the digit in the hundredths place multiplied by 1/100. For example, if the digit in the hundredths place is 5 in the number 0.56, you would express it as 5 * (1/100) in expanded form.

What is the expanded form of a decimal number with five decimal places?

The expanded form of a decimal number with five decimal places would be shown as the sum of the digits multiplied by their corresponding place values, moving from left to right like: (d * 10^1) + (e * 10^0) + (c * 10^(-1)) + (i * 10^(-2)) + (m * 10^(-3)) + (a * 10^(-4)), where d, e, c, i, m, and a represent the digits in the decimal number.

How do you represent the thousandths place in expanded form?

To represent the thousandths place in expanded form, you would write the value as a sum of its digits multiplied by their respective place values. For example, if the digit in the thousandths place is 3, the expanded form would be 3/1000, showing that it represents 3 thousandths.

What is the expanded form of a decimal number with two decimal places?

The expanded form of a decimal number with two decimal places would involve breaking down the number to show the value of each digit's place. For example, the decimal number 23.45 would be expanded as 20 + 3 + 0.4 + 0.05.

How do you express the place value of a decimal number with six decimal places?

To express the place value of a decimal number with six decimal places, you would start from the left of the decimal point with the digit in the 10^-1 (tenths) place, followed by the 10^-2 (hundredths) place, 10^-3 (thousandths) place, 10^-4 (ten-thousandths) place, 10^-5 (hundred-thousandths) place, and finally, the 10^-6 (millionths) place.
