To find the missing number, we can set up the equation based on the information provided:
\[ 800,000,000 + 500,000 + 20 + x = 890,500,020 \]
Where \( x \) is the missing number. We will first calculate the left side without \( x \):
1. Calculate \( 800,000,000 + 500,000 + 20 \):
\[
800,000,000 + 500,000 = 800,500,000
\]
\[
800,500,000 + 20 = 800,500,020
\]
Next, we can input this sum back into the equation:
\[ 800,500,020 + x = 890,500,020 \]
To isolate \( x \), we subtract \( 800,500,020 \) from both sides:
\[
x = 890,500,020 - 800,500,020
\]
Calculating that gives:
\[
x = 90,000,000
\]
Thus, the missing number is \( 90,000,000 \).
\[ 800,000,000 + 500,000 + 20 + x = 890,500,020 \]
Where \( x \) is the missing number. We will first calculate the left side without \( x \):
1. Calculate \( 800,000,000 + 500,000 + 20 \):
\[
800,000,000 + 500,000 = 800,500,000
\]
\[
800,500,000 + 20 = 800,500,020
\]
Next, we can input this sum back into the equation:
\[ 800,500,020 + x = 890,500,020 \]
To isolate \( x \), we subtract \( 800,500,020 \) from both sides:
\[
x = 890,500,020 - 800,500,020
\]
Calculating that gives:
\[
x = 90,000,000
\]
Thus, the missing number is \( 90,000,000 \).
