Answer: pass 12 fail 12 passes 15 fail1 3
Step-by-step explanation:
pass 12 fail 12
pass 15 fail 13
notice that the denominator can be factored into (x-3)(x+3).
Now you can cross out (x - 3) from the numerator and denomiantor resulting in a simplified fraction of

Answer && Step-by-step explanation:
7 yards == 4/4
by simple arithmetic remove 3/4 from 7 until you can no longer obtain 3/4 from it
7 => 6*1/4
6*1/4=>5*2/4
5*2/4=>4*3/4
4*3/4=>4
4=> 3*1/4
3*1/4=>2*2/4
2*2/4=>1*3/4
1*3/4=>1
1=>1/4
1/4 remains and 9 bows were made
