Here are the solutions to the questions stated above:

### 1) What is 100% of 4/5?

Always use this formula to find a percentage:

% / 100 = Part / Whole replace the given values:

100 / 100 = Part / 4/5

Cross multiply:

100 x 4/5 = 100 x Part, or

80 = 100 x Part

Now, divide by 100 and get the answer:

Part = 80 / 100 = 4
