Answer:
Let f_n be the number of rabbit pairs at the beginning of each month. We start with one pair, that is f_1 = 1. After one month the rabbits still do not produce a new pair, which means f_2 = 1. After two months a new born pair appears, that is f_3 = 2, and so on. Let now n 
3 be any natural number. We have that f_n is equal to the previous amount of pairs f_n-1 plus the amount of new born pairs. The last amount is f_n-2, since any two month younger pair produced its first baby pair. Finally we have
f_1 = f_2 = 1,f_n = f_n-1 + f_n-2 for any natural n 3.

Cancel 9/21 to 3/7:
a-3/7-3/7-3
Combine the fractions:
a- 6/7- 3
Convert element to fraction:
3*7/3 - 6/7
Since the denominators are equal combine the fractions:
-3*7-6/7
-3*7-6= -27
