In this case we want to simplify a fraction, which can be considered a grouping symbol.
10-22/8-17 = (10-22)/(8-17)
Therefore, we will evaluate the expressions in the numerator and denominator individually before completing the division.
Numerator
As we can see, there is only subtraction in the numerator, so let's calculate this difference.
10-22= - 12
Denominator
There is also only subtraction in the denominator. Let's calculate this difference, too.
8-17= - 9
Quotient
Finally, combining these two results, we can simplify the given expression.
