Percentage of the applicant to a program were rejected = 80%

Percentage of the applicant to a program were accepted would be =100%-80%

                                                                                                                       =20%

So, The ratio of number accepted to number rejected is given by = 20 : 80

                                                                                                                   = 1 : 4

Hence, the ratio of number accepted to number rejected is 1/4.

Let number be = x 

7/21 of x = 6 

7/21 * x = 6

Multiply by 2 both sides 

14/21 * x = 12
