Question

There are 6 girls in a music class. This represents 3/7 of the entire class. Solve 3/7s=6 to find the number of students ,s, in the class

Answer 1

S is being multiplied by 3/7.
You want s alone, which is the same as s being multiplied by 1.
Multiply 3/7 by its reciprocal, 7/3, to get 1.
You must multiply both sides of an equation by the same number, so multiply both sides of the equation by 7/3.

3/7 s = 6

(7/3)(3/7) s = 7/3 * 6

s = 7/3 * 6/1

s = 42/3

s = 14

There are 14 students in the class.

Answer 2

There are 14 people in the class
