1/4 Divided By 9/10=

Answers

Answer:

$(5)/(18)$

Step-by-step explanation:

When dividing fractions, the formula is simple: Keep Flip Change (KFC)

So keep $(1)/(4)$ change your division sign to a multiplication sign, and flip $(9)/(10)$ so it becomes $(10)/(9)$ .

$(1)/(4)$ · $(10)/(9)$ = $(10)/(36)$

Then you need to reduce your fraction to simplest form.

$(5)/(18)$

5/8 or 0.27

1) what is the meaning of commutative property?2)what is the meaning of distributive property?
3)what is the meaning of associative property?

Answers

Commutative Property- is only applicable to addition and multiplication.
Like- a + b = b + a
That means we can swap numbers in addition.(The answer is the same)
a x b = b x a
That means we can swap numbers in multiplication.(The answer is the same)

Commutative is not applicable to subtraction and division as
a - b (is not) = b - a
And a / b (is not) = b / a

Distributive Property- Means we can distribute a number in to two parts and still get the same answer, applies to only addition and multiplication and-

Here lets take 2 and 4 as examples-

For addition-
2 + 4 + 3 = 9
(2 + 4) + 3 = 9

For multiplication-
2 x 4 x 5 = 40
(2 x 4) x 5 = 40

Associative Property- Means that you may change the order of the numbers but the answer is the same, much like commutative, its just that it applies to more than 3 numbers- (Addition and Multiplication only)

For addition-
2 + 3 + 4 = 9
3 + 2 + 4 = 9 also

For multiplication-
2 x 3 x 4 = 24
4 x 2 x 3 = 24 also

That's it!

Hope I helped!

$Communitive:a+b=b=a \n a*b=b*a \n \n Distributive:a(b+c) = ab+ac \n \n Associative:(1+2)+3=1+(2+3)$

Suppose that a randomly generated list of numbers from 0 to 9 is being used to simulate an event that has a probability of success of 30%. Which of these groups of numbers could represent a success?

Answers

While this question lacks the actual choices, determining the correct answer should be fairly easy. The "probability of success" that is being referred to here is the amount of numbers that will be listed. Since a probability of 30% is being looked for, we only have to choose the choice with 3 of the 10 numbers listed.
