You are probably expected to choose ...
• All integers are rational numbers.
• Terminating decimals are rational numbers.
However, the premise of ...
• 0.278254….. is a terminating decimal, therefore it is a rational number.
is False, so the rules of logic allow any conclusion—meaning the implication is True. (As it happens, a repeating decimal is, in fact, a rational number.) So, this, too, is a true statement.
I've been waiting for someone to ask this question. It's one of my favorite questions to answer.
percent means out of 100 so 1% = 1/100 and 40%=40/100 or 1/25
so for percent of a number, 'of' means multiply so 40% of 500= 40/100 times 500 or 20000/100 or 200
if you multiply a fraction by its recipricol (the number fliped upside down) the you will get 1 so if you multiply 1/2 by 2/1 then you will get 1
thus
percent is out of 100 so 1%=1/100 25%=25/100
if you represent 45 out of something as 45/x then you multiply it by the reciprocal of the fraction that is supposed to be equal (1/2 =2/4) then you will get 1
so 45/x times reciprocal of 100/25 then you will get 1/1 or 4500/25x
so you divide to find x and get 180
so 45 is 25% of 180
The following is extra
as stated above 'of' can be taken as multiply so
45 is 25% of 180 can be rewriten as
45=25/100 times 180
but we don't know that 180 is the answer so we replace it with x then solve for x
Explanation:
The expression is given below as
Concept:
We will apply the bsolute rule below
By applying the concept, we will have
Hence,
The final answer is
