<h3>Answer: the fraction -8/117</h3>

----------------

First, convert to an improper fraction

3 & 1/4 = 3 + (1/4)

3 & 1/4 = (12/4) + (1/4)

3 & 1/4 = 13/4

The mixed number 3&1/4 turns into the improper fraction 13/4

---------------

-2/9 divided by (3&1/4) = -2/9 divided by 13/4

To divide two fractions, you flip the second one and then you multiply

"-2/9 divided by 13/4" turns into "-2/9 times 4/13" after this happens

Then you multiply straight across. The numerators stick together. The denominators stick together.

numerators: -2*4 = -8

denominators: 9*13 = 117

We end up with the fraction -8/117

This cannot be reduced as there are no common factors (other than 1) between 8 and 117.

Unlike credit card purchases, interest charged on cash advances is already incurred even if you pay before the due date. 

32% is the annual interest rate
1 month is the term
200 is the principal

32% / 12 months = 2.67% per month

200 * 2.67% = 5.34 monthly interest

200 * 32% = 64  annual interest
64/12 = 5.33  monthly interest

Notice the tickmark on the angles, those angles are equal to each other.

now, notice the angle at the very top, the large triangle is really sharing it with smaller-inscribed triangle, and therefore is equal on both triangles.

therefore, the larger triangle, is similar with smaller-inscribed triangle by AA.

what the dickens does that mean?

\bf \cfrac{large}{small}\qquad \cfrac{4+5}{4}=\cfrac{5+x}{5}\implies \cfrac{9}{4}=\cfrac{5+x}{5}\implies 45=20+4x&#10;\\\\\\&#10;25=4x\implies \cfrac{25}{4}=x\implies 6\frac{1}{4}=x

Sergeu [11.5K]

Answer:

Step-by-step explanation:Given that the numerator of a given fraction is 4 less than its denominator.

Also given that 3 is subtracted from the numerator and 5 is added to the denominator, the fraction becomes one by fourth .

Let the fraction be  

Since the numerator of a given fraction is 4 less than its denominator we have,

Numerator=Denominator-4

⇒ a=b-4

Since 3 is subtracted from the numerator and 5 is added to the denominator, the fraction becomes one by fourth we have

4(a-3)=1(b+5)

4a-12=b+5

4a-b=17

4(b-4)-b=17   ( ∵ a=b-4)

4b-16-b=17

3b=17+16

3b=33

⇒ b=11

Now put b=11 in a=b-4 we get

a=11-4

⇒  the fraction is a/b=7/11

A box at a miniature golf course contains contains 4 red golf balls, 8 green golf balls, and 7 yellow golf balls. What is the pr
Solnce55 [7]

Answer:

 =57.89%

Step-by-step explanation:

The total number of golf ball is 4+8+7 = 19

P (red or yellow) = number of red or yellow

                              ------------------------------------

                                total number of golf balls

                           = 4+7

                              -----

                              19

                         =11/19

Changing this to a percent means changing it to a decimal and multiplying by 100%

                        = .578947368 * 100%

                         =57.8947368%

Rounding to two decimal places

                         =57.89%
