HEY EVERYBODY! Here is percent.
PERCENT: A percent is an equivalent fraction out of 100.
Our homework is to find the percent of the following fractions in 3 different ways. (I'll cover 1 and leave the rest to you guys).
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
5/7
One way to find the percent of this fraction is by first, converting it to a decimal. In order to find the decimal equivalent of a fraction, we multiply the numerator by the denominator.
5 divided by 7 = 0.71
Now that we have the decimal, we have to find the percent, by multiplying the decimal by 100. We multiply by 100 because, remember a percent is an equivalent fraction out of 100. A decimal is an equivalent fraction out of 1, so in order to get from 1-100 we multiply by 100.
0.71 X 100 = 71%
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Another way to find percent is by creating an equivalent fraction out of 100. In order to get from 7-100 we have to multiply by 14.2. And remember, what you do to the top, you do to the bottom.
5 X 14.2 = 71
Now our fraction is 71/100
This means that our percent is 71%
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
A third way to figure out percent is by using ratio.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
So there is 3 different ways to figure out percent. Have fun with the rest!
