12 songs

Step-by-step explanation:

Brenda's band plays songs in sets of 4

Melissa's band plays songs in sets of 6.

After performing together, both bands realize that they have played the same number of songs.

What is the smallest number of songs each band could have performed?

The smallest number of songs each band could have performed can be calculated by finding the lowest common multiple of 4 and 6

4 = 8, 12, 16, 20, 24, 28, 32, 36, 40

6 = 12, 18, 24, 30, 36, 42

The lowest common multiple of 4 and 6 is 12

The smallest number of songs each band could have performed is 12 dongs
