Lesson 3: Decimals in expanded form

# Write decimal in expanded form

To write a decimal in expanded form, we need to break down each digit according to its place value. Start with the whole number portion, identifying the hundreds, tens, and ones places. Then, move on to the tenths, hundredths, and thousandths places. Keep in mind the order of operations when combining the expanded terms. Created by Sal Khan.

• Why did you say point on this video instead of saying and?The right way to say a decimal is and.
• Either way is correct. Generally when you write decimals out in words you will say "and", and when you write them in numbers you will say "point".

• imagine
• 1 upvote=1 banana for a starving monkey🐒
• Why the left side of decimal is once and other right side is tenths
• because there are such a thing as a ones digit (1,2,3,4,5,6,7,8,9), but there is no such thing as a oneths digit. .1 = 1/10 (one tenth) .2 = 2/10 (two tenths) etc.
• how do you even make a project?
• how did you type so fast
• Why when you did the seven hundredth you put it in a fraction. Why is that
• Because decimals are a fraction. In expanded form, we write each digit with its corresponding place value. All the decimal digits have place values that are fractions.
