# How do you use the distributive property to calculate 6(19.99) in your head?

May 28, 2018

Here's how I did it:

#### Explanation:

First, we know that $19.99$ is almost $20$, or $0.01$ away from it to be exact.

So our expression can be rewritten as $6 \left(20 - 0.01\right)$.

Now, we use the distributive property to simplify that:

Following this image, we know that:
$\textcolor{b l u e}{6 \left(20 - 0.01\right) = \left(6 \cdot 20\right) + \left(6 \cdot 0.01\right) = 120 + 0.06 = 120.06}$

So the answer is $120.06$.

Hope this helps!
