How To: The key words in this problem are "What Percent" because they let us know that it's the Percent that is missing. So the two numbers that it gives us must be the "Total" and the "Part" we have.
Part/Total = Percent
In this case, it's the Total that our uncle owned. So we put 300 on the bottom of the fraction and 21 on top. Now we're ready to figure out the part we don't know; the Percent.
21/300 = Percent
To find the percent, all we need to do is convert the fraction into its percent form by multiplying both top and bottom part by 100 and here is the way to figure out what the Percent is:
21/300 × 100/100 = 7/100
7 = Percent
And that means he has 7 percent of the shares of his company now.
