The standard form of (-8/-36) is ________________.
The standard form of 18/-24 is _____________.
On a number line, -½ is to the ______ of zero (0).
On a number line, 4/3 is to the __________of zero (0).

-16/24 and 20/-16 represent ________ rational numbers.
-27/45 and -3/5 represent ___________ rational numbers.
Additive inverse of 2/3 is ______.
(-3/5) + (2/5) = ________.
(-5/6) + (-1/6) = _________.
(3/4) × (-2/3) = __________.
(-5/3) × (-3/5) = ________________.
(1/2) = (6/ __________)

(8/8) [[ ]] ((2/2)
The reciprocal of ______ does not exist.
The reciprocal of 1 is ______.
(-3/7) ÷ (-7/3) = _______.
0 ÷ (-5/6) = ___________.
0 × (-5/6) = ___________.
___________ × (-2/5) = 1
The standard form of rational number –1 is ______.
If m is a common divisor of a and b, then (a/b) = (a ÷ m)/ ________.
If p and q are positive integers, then p/q is a ______ rational number and – p/q is a ______ rational number.
Two rational numbers are said to be equivalent or equal if they have the same ______ form.
If p/q is a rational number, then q cannot be ______.
Every natural number is a rational number but every rational number need not be a natural number.
Zero is a rational number.
Every integer is a rational number but every rational number need not be an integer.
Every negative integer is not a negative rational number.
If p/q is a rational number and m is a non-zero integer, then
(p/q) = (p × m)/(q × m)
If p q is a rational number and m is a non-zero common divisor of p and q, then
p/q = (p ÷ m)/(p ÷ m)
In a rational number, the denominator always has to be a non-zero integer.
If p/q is a rational number and m is a non-zero integer, then (p/q) = (p × m)/(q × m) is a rational number not equivalent to p/q.
The Sum of two rational numbers is always a rational number.
