Expanded Form is a way to break up a number to show how much each digit in the number represents. In other words, expanded form is the method of pulling a number apart and expressing it as a sum of the values of each digit.
Example: 485
400+80+5
Expanded form- let's say you have the number 432, you would write it out just how it is said 400+30+2 Word form- you just write it out four hundred thirty two
Eight hundred three (800 + 3).
Say you are using 1,400,782 1st one 1,000,000+400,000+700+80+2 2nd one million four hundred thousand sven hundred eighty two 3rd 1,400,782
When you say "and" while stating a number it signifies a decimcal point. Thus: the number is 6.7433 6.7433 is writing it as a decimal. Standard form is to write the solution as a fraction:
When saying the number 0.125, you would say "nought" (or "zero") "point one two five".
Expanded form- let's say you have the number 432, you would write it out just how it is said 400+30+2 Word form- you just write it out four hundred thirty two
you just take a number of any form lets say 120, basically pull the number apart in sections and add it. like so 100+20lets so another how about, 789? you go 700+80+9
3.4 in expanded form = (3 x 1) + (4/10)
The number in words is... forty million, two hundred (and) thirty thousand (and) thirty-two.
I would say they are in standard form, but I would be more likely just to ask you to write a simplified number without using exponents. The terminology can vary, but the following example shows the usual names: 1,023 is in standard form. One thousand twenty-three is in word form. 1000 + 20 + 3 is in expanded form.
Seventy and thirty-nine thousandths.
Writing a number in standard form simply means to express the number in its 'normal' form. Therefore, the way you wrote the number is the standard form for your example. You could also write it with comma separators: 9,876,543,210
Eight hundred three (800 + 3).
3.21 = 321/100. That is the number in the form of the simplest fraction though I would not say that is a simpler form than 3.21!
Say you are using 1,400,782 1st one 1,000,000+400,000+700+80+2 2nd one million four hundred thousand sven hundred eighty two 3rd 1,400,782
Five hundred six thousand, seven hundred nine.
The answer is 20 and they are: 1,2,3,4,5,6,7,8,9,10,20,30,40,50,60,70,8… and 200 The reason is the expanded form of lets say 11 is 10+1 in which case it is not identical to its standard form. Numbers such as 30 is only 30 and is identical to its standard form.
