Si al numerador de una fraccion se añade 5, el valor de la fraccion es 2, y si al numerador se resta 2, al valor de la fraccion
konstantin123 [22]

Answer:

Respuesta.- La fracción es 9/7

Step-by-step explanation:

1) Llamando X e Y a la fracción, tenemos: X/Y

Si al numerador se le añade 5, es decir X+5, el valor de la fracción es 2, luego:

(X+5)/Y = 2

Y si al numerador se le resta 2, es decir X-2, el valor de la fracción es 1, luego:

(X-2)/Y = 1

Juntando amabas ecuaciones:

(X+5)/Y= 2

(X-2)/Y = 1

Despejando Y en ambas:

Y = (X+5)/2

Y = (X-2)..........(1)

Igualandolas:

(X+5)/2= (X-2)

De donde:

X+5 = 2X-4

X = 9

Y finalmente, sustituyendo el valor de X = 9 en la ecuaión (1), tendremos:

Y = (X-2)

Y = (9-2)

Y = 7

Respuesta.- La fracción es 9/7

3. 36 percent of 18 is 18 percent of what number?
Fiesta28 [93]

Answer:

The required number is 3.36.

Step-by-step explanation:

To find : 3.36 percent of 18 is 18 percent of what number?

Solution :

Let the required number be 'x',

According to question,

3.36 percent of 18 is 18 percent of x,

i.e. 3.36\%\times 18=18\%\times x

\frac{3.36}{100}\times 18=\frac{18}{100}\times x

x=\frac{3.36\times 100}{100\times 18}\times 18

x=3.36

So, 3.36 percent of 18 is 18 percent of 3.36,

Therefore, The required number is 3.36.

If 11,000 is 85% of what was in my bank account, how much did I originally have?
Mrrafil [7]
You can set it up like a proportion:

\frac{11000}{0.85}    \frac{x}{1.00}

Cross multiply: 
11000*1 = 11000
11000/0.85 = 12,941.18

You had roughly $12,941.18 in your bank account.
