Answer 2

Answer:

16

Step-by-step explanation:

no. of girls who started riding to school this year= 8

                                                                                = 2/3 of 3/4 of the whole group of girls

therefore,

2/3 * 3/4 = 1/2

whole group of girls is x

1/2 of x = 8

so x = 16
