1 1/5 as a percent:
6/5 x 100 = %
1.2 x 100 = 120 % look at the answer to se if it makes sense in a case like this one. With this problem you could almost look at this as two parts.
(1 x 100) + (1/5 x 100) = 100% + (0.20 x 100) = 100% + 20% = 120%
Another example:
2 1/2: You can do it two ways as long as you understand them:
2 1/2 = ((2 x 2) + 1)/2 = (4 + 1)/2 = 5/2 = 2.5 x 100 = 250% that's 2.5x bigger, better, etc.
The other way: 2 1/2 = (2 x 100) + (1/2 X 100) = 200 + (0.50 x 100) = 200 + 50 = 250%
They are the same. You just have to not be so locked up in formal equations. Understand the concept of percentage. Good Luck!
