A terminal zero is a $0$ that appears at the end of a number. For example, the number $3,800$ has two terminal zeros.
How many terminal zeroes does $40 \cdot 6 \cdot 75 \cdot 12$ have?

Let's identify all the ways we can get a terminal 0. 

First, since 40 has a terminal 0, we already have 1. 

Since 7512 also has a terminal 0, which makes it 2. 

 

Lastly, 675 has one terminal 0, making 3. 

We could also multiply everything out. We have

4067512=216000

 

As shown, there are 3 terminal 0s. 

 

So 3 is our answer. 

 

Thanks! :)
