# Write the steps for how to use a number line to multiply a 2-digit number by 20.

**Solution:**

A straight line that has all real numbers is known as the number line.

So, the steps involved in multiplying a 2-digit number by 20 are as follows.

- First multiply the two digit number by 2 and get the result.
- 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 involved in multiplying 15 by 20 on the number line.

**Step1:**

Multiply 15 by 2 as,

A = 15 × 2 = 30

Make 2 jumps of 15 to get 30.

**Step2:**

Multiply 30 to 10 then we get,

B = 30 × 10 = 300

Now make 10 jumps of 30 to get 300.

Therefore, the steps for how to use a number line to multiply a 2-digit number by 20 are mentioned above.
