A,B,C,D,E are 5 letters so you must divide 45 by 5. Equaling 9. so 9 over 45 in fraction form. But you need to simplify it so you divide the numerator and denominator by 3. Therefor creating 3 over 15 in fraction form. Then you divide both again by 3. Creating 1 over 5 of course in fraction form. Finally you divide 1 by 5 Equaling .2 or in another form .20. So you answer is .20
TADA!!! YOUR WELCOME I WORKED REALLY HARD TO DO THIS LMAOO
