To obtain the multiplication of \(2\) digits number by \(20\) first jump two times the \(2\) digit number then jump \(10\) times by the result we get in step 1.
Further explanation:
A straight line that has all real numbers is known as number line.
The steps involve in multiplying 2-digit number by \(20\) are as follows.
1. First multiply the two digit number by 2 and the get the result.
2. Multiply the result by \(10\) to obtain the final result.
For example we have to multiply \(15\) by \(20\) on the number line.
Following are the steps involve in multiply \(15\) by \(20\) on the number line.
Step 1
Multiply 15 by 2 as,
\(\begin{gathered}A = 15 \cdot 2 \\= 30 \\ \end{gathered}\)
Make 2 jumps of 15 to get 30.
Step 2
Multiply \(30\) to \(10\) to obtain the final result.
\(\begin{gathered}B = 30 \cdot 10 \\ = 300 \\ \end{gathered}\)
Now make 10 jumps of 30 to get \(300\).
To obtain the multiplication of 2 digits number by \(20\) first jump two times the 2 digit number then jump \(10\) times by the result we get in step 1.
