Question

Write the following numbers in standard and expanded form in International system:

Fifty-six million.

Answer 1

Step 1: Write the number in standard form.

Given number: Fifty-six million.

Place value chart for fifty-six million.

Ten millions	Millions	Hundred thousands	Ten thousands	Thousands	Hundreds	Tens	Ones
$5$	$6$	$0$	$0$	$0$	$0$	$0$	$0$

We know that in the International system, the first comma is placed after the hundreds place and then commas are placed after every three digits.

So, the given number in standard form in international system $=56,000,000$

Step 2: Write the expanded form of given number.

$$\begin{gathered} \mathrm{TM}\mathrm{M}\mathrm{HTh}\mathrm{TTh}\mathrm{Th}\mathrm{H}\mathrm{T}\mathrm{O} \\ 56000000 \\ \Rightarrow 5\times 10000000+6\times 1000000+0\times 100000+0\times 10000+0\times 1000+0\times 100+0\times 10+0 \\ =50000000+6000000. \end{gathered}$$

Hence, the standard form of the given number in international system is $56,000,000$

and the expanded form of the given number is $50000000+6000000$.
