un estudiante esta revisando las evidencias de clase que mando a la maestra durante el trimestre si la maestra solicito 20 evidencias y el mando solamente 12 en que porcentaje cumplió con el trabajo

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

= 42 × 20

= 840

its b) 840✌✌✌
