Answer 1

The number of good guys is 75.

Explanation:

Given:

The ratio of "good guys" to "bad guys" on a high school teaching faculty is 5 to 1.

There are 90 teachers in the high school.

Now, to find the number of good guys.

Let the number of good guys be
`5x.`

And the number of bad guys be
`1x.`

Total number of teachers = 90.

According to question:

`5x+1x=90.`

`6x=90`

`x=15.`

Now, to get the number of good guys:

`5x`

Putting the value of x we get:

`5* 15=75.`

Therefore, the number of good guys is 75.
