Answer 2

Answer:

4 messages of 10% of the messages were not birthday greetings.

Step-by-step explanation:

Total messages = 40

Percent of birthday greetings = 90%

Number of birthday greetings = 90% of 40

                                                 = 36

Number of other messages = 40 - 36

                                              = 4

Percent of other messages = 4/40 × 100

                                              = 10%
