2/7 of 49 = 14
3/7 of 49 = 21
(since 1/7 of 49 is 7)

There are 14 students are in band and 21 students in sports in each activity.
What is the unitary method?
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Given that classroom of 49, if 2/7 of the students are in the band and 3/7 play sports.
First, WE need to divide 49 by 7. then we can know the value of 1/7 in people.
49 / 7 = 7
1/7 is 7 people.
Now We multiply the numerator by 7
2 x 7 = 2/7
=14 students are in band.
3 x 7 = 3/7
=21 students in sports.
Therefore, There are 14 students are in band and 21 students in sports in each activity.
