In finding the percentage... Multiply the base and the rate.

ex. A toy store was on sale. All of the toys there are in discount of 30%. A toy that costs 70.00 will be on_______.

$70.00 =============================> BASE

30%==============================>RATE

??===============================>PERCENTAGE

First make the rate into decimal.... just remove the percent sign and place a decimal point 2 moves from the left.... 30%=0.30

then multiply the base and rate.... 70.00 x 0.30= 21.00

remove the two zeros become ... 21

that's the answer $21

If there's a confusion on my explanation... ASK ME!! :D
