Calculating Ratio of Large Envelopes to Total

To find the ratio of large envelopes to the total number of envelopes, first determine the total number of envelopes by adding the number of large envelopes to the number of small envelopes. Large envelopes: 6 Small envelopes: 11 Total number of envelopes: 6 + 11 = 17 Now find the ratio of large envelopes to the total number of envelopes, which is 6 to 17. The ratio is written as: 6:17 So the correct answer is C: 6:17.
