You type at a speed of 32.5 words per minute. your teacher types 2.4 times faster than you. what is your teacher's typing speed?

Multiply 2.4 by 32.5.

      32.5
   x   2.4

     1300
+   650

     7800

We get 7800, but we are not done yet.
Now we need to place the decimal point.
32.5 has 1 decimal place. 2.4 has 1 decimal place.
Add the decimal places to get 2 decimal places.
We must place a decimal point on 7800 to create two decimal places.
We start from the last zero at the right and count two decimal places to the left.
We place the decimal point to the left of the left zero.
The answer is 78.00
Since final zeros after the decimal place have no value, the answer is simply 78.

The teacher types at 78 words per minute.
