3/7 of 49 = 21

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.
