There are an infinite number of decimal place values. Last year, a Japanese team,
using a supercomputer, calculated the value of "pi" out to 4 trillion decimal places.
The first seven places after the decimal point are:
tenths
hundredths
thousandths
ten-thousandths
hundred-thousandths
millionths
ten-millionths
0.37 The 3 is in the tenths place, the 7 is in the hundredths place.
a European mathematician did it two or three centuries ago. before then they used fractions instead of decimals.
Represent numerical values.
Place value helps in subtracting decimals by ensuring that digits are aligned according to their respective values—tenths, hundredths, etc. This alignment allows for accurate borrowing and subtraction, similar to whole numbers. By maintaining the correct place values, it becomes easier to manage differences and ensure precision in the result. Ultimately, a clear understanding of place value is essential for performing decimal subtraction correctly.
Seven hundreths is 0.07
0.37 The 3 is in the tenths place, the 7 is in the hundredths place.
Align the numbers according their place values. Go from left to right (decreasing place values) until the face values of the numbers are different. Then the number with the larger face value in that place is the larger number.

By doing this it aligns all the place values so you can clearly add or subtract the correct place values and get a correct answer. You might say it is an organization technique. Of course if you use a calculator, this is not necessary.

To show values less than 1.
Seven hundreths is 0.07
Decimals until you get to values with over nine decimal places, then fractions are more exact
7.009
No ones or units, no tenths but seven hundredths = 7/100
To order decimals on a number line, first identify the place values of the decimals, focusing on the tenths, hundredths, and thousandths as needed. Begin by comparing the whole numbers; if they are the same, move to the next decimal place until you can determine the order. Plot each decimal on the number line according to its value, ensuring that smaller decimals are positioned to the left and larger ones to the right. This visual representation allows for easy comparison and ordering.
