In order to solve this question, we need to set up a proportion. We are trying to solve for a percentage, so the proportion will be 22/28 = x/100, where x is the percentage that 22 is out of 28. 

22 / 28 = x / 100
2200 = 28x   Cross multiply
x = 78.6%   Divide

22 is about 78.6% of 28. Remember that, whenever you need a percentage, just set up a proportion like this one.

Hope this helps!
