We must transform the mixed numbers to the improper fraction.

5\dfrac{1}{4}=\dfrac{5\cdot4+1}{4}=\dfrac{21}{4}\\\\-2\dfrac{1}{4}=-\dfrac{2\cdot4+1}{4}=\dfrac{9}{4}

Calculate a product:

\left(5\dfrac{1}{4}\right):\left(-2\dfrac{1}{4}\right)=\dfrac{21}{4}:\left(-\dfrac{9}{4}\right)=-\dfrac{21}{\not4_1}\cdot\dfrac{\not4^1}{9}=-\dfrac{21:3}{9:3}=-\dfrac{7}{3}

Answer:

-7/6

Step-by-step explanation:

That'd be 21/4 divided by -9/2, or, equivalently, 21/4 times -2/9.

From this we get -42/36, which, when reduced, yields -7/6.

Answer:

  3/5

Step-by-step explanation:

Let a, b, c represent the probability of a win by Kaden, Keith, and Kipp, respectively.

  P(bc' | a') = P(a'bc')/P(a')

  P(bc' | a') = (1/2)/(1 -1/6) = (3/6)/(5/6) = 3/5

The probability is 3/5 that Keith beats Kipp when Kaden doesn't win.

There are 81 red, blue and yellow
wel

Step-by-step explanation:

Here Given

Total counters = 81

red counters are 9 more than the yellow ones.

And Yellow counter = blue counter

So let the Yellow counter be x and as blue counter and yellow counter are same then blue counter will be also x

And by the question

Red counter = 9 + x

Now

9 + x + x + x = 81

9 + 3x = 81

3x = 81 - 9

3x = 72

x = 72 / 3

Therefore x = 24

Now

Red counters = 9 + 24 = 33

Blue counters = 24

Yellow counters = 24

Hope it helped :)
