What is 5 percent of 220000?
A percentage is simply a proportion per 100. 5 percent means 5 per 100. We can write this as a fraction; 5/100. To then calculate 5 percent of 220,000 we simply multiply the value by the fraction. 5/100 * 220,000 = 11,000.
How do you do proportions?
A propotion is a math method. For example 3 over 100 = x over 50, you crossmultipy both 3 times 50 and 100 times x, then you'll get 150 = 100x, then you have to get x by itself so you divide 100 from both sides and that leaves you with x = 1.5 The proportion in this problem is 3 over 100 = x over 50

What is the purpose of the sample proportion?
