To determine

To write each number as a whole number using digits

Answer to Problem 385RE

$1,043,922,311$

Explanation of Solution

Given information:

One billion, forty-three million, nine hundred twenty-two thousand, three hundred eleven

Concept used:

To write a whole number using digits:

• Identify the words that indicates periods
• Draw three blanks to indicate the number of places needed in each period. Separate the periods by commas
• Name the number in each period and place the digits in the correct place value position

In order to write the given whole number using digits, we will identify the words that indicate periods. Except for the first period, all other periods must have three places. Draw three blanks to indicate the number of places needed in each period. Separate the periods by commas and write the digits in each period as per their place values. So we get

$\begin{array}{l}\stackrel{\text{Billions}}{\overbrace{\text{one}}},\stackrel{\text{Millions}}{\overbrace{\text{forty-three million}}},\stackrel{\text{Thousands}}{\overbrace{\text{nine hundred twenty-two thousand}}},\stackrel{\text{ones}}{\overbrace{\text{three hundred eleven}}}\\ \downarrow \downarrow \downarrow \downarrow \\ \underset{\_}{}\underset{\_}{}\underset{\_}{1}\underset{\_}{0}\underset{\_}{4}\underset{\_}{3}\underset{\_}{9}\underset{\_}{2}\underset{\_}{2}\underset{\_}{3}\underset{\_}{1}\underset{\_}{1}\end{array}$

Therefore, the number is $1,043,922,311$.
