What percentage did you tip if your lunch was $10 and you left $2

you are a great person you tiped 20%.

That's a 20% tip.

Step-by-step explanation:

First, let's turn the problem into a fraction in order to later divide the fraction to find the percentage. It would look like this:

Divide 2 by 10:

.2

Change to a percentage:

20%

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
