Find percentage

Let us study how to find percentage,

You have 120 cows and 90% of them are female. How many female cows do you have?

In order to find the answers to questions like the one above, you need to know how to do this kind of calculation:

90% of 120

You also need to understand that when you find a percent of something, the answer has the same units as the number you are finding the percent of. For example:
50% of 200 carrots is 100 carrots 10% of $300 is $30 25% of 80 units is 20 units

Now let's look at the methods for finding a percent of a number:

Method 1 involves using the fraction instead of the percent. For example, if you were asked:

"What is 50% of 36?"

you would instead ask yourself:

"What is half of 36?"

This makes it easy to get the answer 18.

I hope the above explanation was useful, now let me explain about Fractions.
