You multiply two rational numbers by multiplying numerators and denominators with each other. So, you have
A rational number is a fraction where both numerator and denominator are integers. Since the product of two integers is an integer, the result fraction is also a rational number, because both 
and 
are integers.
Step-by-step explanation:
by which method defination method, prime factorization or division method
If it is g(x) composed of f(x): 1 If it is g(x) times f(x): -27
(g•f)(-3) is multiplication, (gof)(-3) is composition.
It’s just 5 you divide 9 into 45 and get a whole number of 5
Step-by-step explanation:
The answer is C
We can easily eliminate B and D since Ms. Macdonald isn't starting with 3 rabbits.
We can also eliminate choice A, because 5 to the 3rd power isn't 15.
5 to the 3rd power is 125, therefore the choice is C
