Answer 1

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

1. Chocolate Donuts:

   • There are \( \frac{40}{100} \) of the donuts that are chocolate.
   • This means there are \( 40 \) chocolate donuts.

2. Glazed Donuts:

   • There are \( \frac{3}{10} \) of the donuts that are glazed.
   • Since \( \frac{3}{10} \) of 100 is \( 30 \), there are \( 30 \) glazed donuts.

3. Total of Chocolate and Glazed Donuts:

   • Total chocolate and glazed donuts = \( 40 + 30 = 70 \).

4. Cinnamon Donuts:

   • Total donuts = \( 100 \).
   • Therefore, cinnamon donuts = Total donuts - (Chocolate + Glazed) = \( 100 - 70 = 30 \).

5. Fraction of Cinnamon Donuts:

   • The fraction of donuts that are cinnamon is \( \frac{30}{100} \).

So the answer is 30/100.
