A number written in the form p/q where p and q are integers and q ≠ 0 is called:
Whole number
Natural number
Rational number
Complex number
The set of all rational numbers is denoted by:
R
Q
N
W
If p/q is a rational number and m is a common divisor of p and q, then p/q =
(p × m)/(q × m)
(p ÷ m)/(q ÷ m)
p + m / q + m
pq / m
To compare rational numbers p/q and r/s, we check:
p compared to q and r to s
ps compared with rq
p + q with r + s
pq with rs
For any rational numbers a and b, a − b =
a + b
a + (−b)
b − a
a × b
The product of two rational numbers is:
Sum of numerators / sum of denominators
Product of numerators / product of denominators
Product of denominators / product of numerators
None
If a/b and c/d are rational numbers, then a/b × c/d =
ac / bd
ab / cd
ad / bc
(a + c)/(b + d)
If x and y are rational numbers and y ≠ 0, dividing x by y means multiplying x by:
y
0
Reciprocal of y
x – y
