Answer 1

They lost `27.28%` of the games.

Explanation:

To find the percentage of the games they lost, you first have to find the percentage of the games they won.

Find the percentage of the games they won:

`16/22*100=72.72%`

Then subtract the amount of games they won from 100%. This is because you want to find the amount of games they lost out of all the games they played (i.e. 100%).

`100%-72.72%=27.28%`

Therefore, they won `72.72%` of the time and lost `27.28%` of the time.

Answer 2

`27.3%`

Explanation:

If the Storms won `16` out of `22` games, they must have lost the other `6` games.

So the question is: what percent of 22 is 6?

To turn that question into an equation, here are some helpful tips:

1. "Is" means "equals", so wherever you see "is", use a `=` sign.
2. "Of" means "multiplication", so use a `xx` sign when you see that word.
3. Use variables for the things you do not know. Since the percent is not known, I will call it `x`.
4. A percent of a number is the same as that number over 100. Since the percent is not known, it will be represented by `x/100`

`stackrel(x/100)overbrace"What percent"stackrel(xx)overbrace"of"stackrel(22)overbrace"22"stackrel(=)overbrace"is"stackrel(6)overbrace"6"`

`x/100 xx 22 = 6`

`x/100 = 6 -:22`

`x/100 = 0.bar(27)`

`x = 27.bar(27)% = 27.3%`

The Storms lost `27.3%` of their games.
