To find the fraction of the donuts that were cinnamon, we first need to determine how many donuts were cinnamon.

  1. The total number of donuts is 100.
  2. The number of chocolate donuts is 40.
  3. The number of glazed donuts is 31.

Now, let's find out how many donuts are cinnamon:

Total donuts = Chocolate donuts + Glazed donuts + Cinnamon donuts
100 = 40 + 31 + Cinnamon donuts

Now, we can solve for the number of cinnamon donuts:

Cinnamon donuts = 100 - (40 + 31)
Cinnamon donuts = 100 - 71
Cinnamon donuts = 29

Now, we can express the number of cinnamon donuts as a fraction of the total number of donuts:

Fraction of cinnamon donuts = Number of cinnamon donuts / Total number of donuts
Fraction of cinnamon donuts = 29 / 100

Looking at the provided options, the correct answer is:

29/100 which is how many of the donuts were cinnamon. (Note that this specific option wasn't listed; please check whether you might have miswritten any of the original options).
