Answer:
(a) If r is any rational number and s is any irrational number, then r/s is rational
(b) The statement is false when r is 0
Step-by-step explanation:
Given
rational number
irrational number
irrational number
Solving (a): The negation
To get the negation of a statement, we only need to negate the end result
In other words, the number type of r and s will remain the same, but r/s will be negated.
So, the negation is:
rational number
irrational number
rational number
Solving (b): When r/s is irrational is false
Given that:
irrational number
Set r to 0
So:

-- rational
<em>Hence, the statement is false when r is 0</em>
Answer:
44.5%
Step-by-step explanation:
THis is because 4/9x100=44.5, which means that 44.5% of the tiles are white
N = 5P + 4
N - 4 = 5P
(N - 4) / 5 = P or (N/5) - 4/5 = P
