if 5/17 of a region was shaded wat part is not?

17/17 - 5/17 = ?

12/17??

correct

To find out what part of the region is not shaded, we need to subtract the shaded part (5/17) from the whole region (1 whole).

The expression to calculate the part of the region not shaded would be: 1 - 5/17.

To simplify this calculation, we need to find a common denominator for 1 and 17. The common denominator is 17, which means we need to express 1 as 17/17.

So the expression becomes (17/17) - (5/17).

Subtracting the numerators (the numbers on top) while keeping the denominator the same (17), we get:

(17 - 5) / 17 = 12/17.

Therefore, 12/17 of the region is not shaded.
