Question

Answer 1

To find the unit rate of letters per envelope, you need to divide the total number of letters by the number of envelopes.

Given:
- Total letters = 45
- Total envelopes = 5

Unit rate = Total letters ÷ Total envelopes
Unit rate = 45 ÷ 5 = 9

Thus, there are **9 letters per envelope**.
