Respuesta :
To obtain the multiplication of [tex]2[/tex] digits number by [tex]20[/tex] first jump two times the [tex]2[/tex] digit number then jump [tex]10[/tex] 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 [tex]20[/tex] are as follows.
1. First multiply the two digit number by 2 and the get the result.
2. Multiply the result by [tex]10[/tex] to obtain the final result.
For example we have to multiply [tex]15[/tex] by [tex]20[/tex] on the number line.
Following are the steps involve in multiply [tex]15[/tex] by [tex]20[/tex] on the number line.
Step 1
Multiply 15 by 2 as,
[tex]\begin{gathered}A = 15 \cdot 2 \\= 30 \\ \end{gathered}[/tex]
Make 2 jumps of 15 to get 30.
Step 2
Multiply [tex]30[/tex] to [tex]10[/tex] to obtain the final result.
[tex]\begin{gathered}B = 30 \cdot 10 \\ = 300 \\ \end{gathered}[/tex]
Now make 10 jumps of 30 to get [tex]300[/tex].
To obtain the multiplication of 2 digits number by [tex]20[/tex] first jump two times the 2 digit number then jump [tex]10[/tex] times by the result we get in step 1.
