Answer 2

Number of Singers in the Concert

To determine the number of singers who participated in the school concert, we need to subtract the number of dancers and reciters from the total number of participants.

Given: - Total number of participants: 35 - Number of dancers: 14 - Number of reciters: 7

To find the number of singers, we can use the following formula:

Number of singers = Total number of participants - Number of dancers - Number of reciters

Using this formula, we can calculate the number of singers in three different ways:

1. First Method: Number of singers = 35 - 14 - 7 = 14

2. Second Method: Number of singers = Total number of participants - (Number of dancers + Number of reciters) = 35 - (14 + 7) = 35 - 21 = 14

3. Third Method: Number of singers = Total number of participants - Number of dancers - Number of reciters = 35 - 14 - 7 = 14

Therefore, there were 14 singers who participated in the school concert.
