Question

How do you write 770, 070 in expanded form

Answer 1

When you determine the place value of a number, you usually start from right to left. The order is as follows:
units (a number followed by no zeroes), tens (a number followed by 1 zero), hundreds (a number followed by 2 zero), thousands (a number followed by 3 zero), ten thousands (a number followed by 4 zero) and finally a hundred thousands (a number followed by 5 zero).

Based on this:
770, 070 in expanded form is:
(7x100000) + (7x10000) + (0x1000) + (0x100)  + (7x10) + (0) 

Answer 2

770,070 = 700,000 + 70,000 + 70

Or

770,070 = (7 x 100,000) + (7 x 10,000) + (0 x 1,000) + (0 x 100)  + (7 x 10) + (0 x 1)

Further explanation

There are four types of number forms:

• Standard form ⇒ written in number form
• Unit form ⇒ writing a number using place value units
• Word form ⇒ written in words
• Expanded form ⇒  stretch it out by place value

The key question is how to write the expanded form from 770,070 but we will set down all the other types.

$\boxed{\boxed{\boxed{.}}}$

$\boxed{ \ Standard \ Form \ }$

770,070 is already a standard form or standard notation.

$\boxed{\boxed{\boxed{.}}}$

$\boxed{ \ Unit \ Form \ }$

Place values:

• hundred thousands = 7
• ten thousands = 7
• one thousands = 0
• hundreds = 0
• tens = 7
• ones (or units) = 0

Hence, the unit form 770,070 is 7 hundred thousands 7 ten thousands 7 tens

$\boxed{\boxed{\boxed{.}}}$

$\boxed{ \ Word \ Form \ }$

From the unit form above, we immediately state the word form as seven hundred seventy thousand seventy.

$\boxed{\boxed{\boxed{.}}}$

$\boxed{ \ Expanded \ Form \ }$

Expanded form represent a way to write numbers by presenting the value of each digit. The expanded form of a number is the same number composed as the sum of each digit according to its place value. Writing decimals in the expanded form is similar to writing whole numbers in expanded form.

$\boxed{ \ 770,070 = 700,000 + 70,000 + 70 \ }$

Or

770,070 = (7 x 100,000) + (7 x 10,000) + (0 x 1,000) + (0 x 100)  + (7 x 10) + (0 x 1)
