If 5/17 of a region is shaded, what fraction is not shaded?

17/17 - 5/17 = 12/17

17/17 which is 1

- 5/17

To find the fraction that is not shaded, we need to subtract the fraction that is shaded from 1.

Given that 5/17 of the region is shaded, we can subtract this fraction from 1:

1 - 5/17

To subtract fractions, we need a common denominator. In this case, we can multiply both the numerator and denominator of 5/17 by 17 (the denominator of the other fraction):

1 - (5/17)*(17/17)
1 - (85/289)

Now, subtract the fractions:

1 - 85/289

To simplify the fraction further, we can find a common denominator of 289 and subtract the numerators:

(289 - 85) / 289

= 204/289

So, the fraction that is not shaded is 204/289.
