Given that The band learns a new song every four days.
We need to find the number of new songs for four weeks.
We know that one week= 7 days
Multiply by 4 to find the number of days in four weeks.
We need to find the number of new songs that the band learns in 28 days.
Divide 28 by 4 to find the number of songs since the band learns one new song every 4 days.
The band learns 7 songs in four weeks.
