Answer:

The answer is 25/24 or 1.041

Step-by-step explanation:

Given 5/6 and 5/8, you can't find the sum at that point. This means we will have to find a common denominator, which will be 24.

6 x 4 = 24 and 8 x 3 = 24

Doing this, you will have to multiply the numerator and denominator by the value the denominator needs to be multiplied by to get 24.

5/6 x 4/4 = 20/24 and 5/8 x 3/3 = 15/24

After getting these values, you can then add them.

20/24 + 15/24 = 25/24 or 1.041

Answer:

The fraction is $\frac{7}{1}$

Step-by-step explanation:

Let the numerator be x and denominator be y

So, Fraction = $\frac{x}{y}$

Now we are given that numerator and denominator of the fraction is increased by 2 and 1 respectively. it becomes 3/4

So, Fraction becomes : $\frac{x+2}{y+1}=\frac{3}{4}$

$4(x+2)=3(y+1)$

$4x+8=3y+3$

$4x-3y+5=0$ ----1

We are also given that the numerator and the denominator are decreased by 2 and 1 respectively , it becomes 1/2

So, Fraction becomes : $\frac{x-2}{y-1}=\frac{1}{2}$

$2(x-2)=y-1$

$2x-4=y-1$

$2x-y-3=0$ ---- 2

Substitute the value of y from 2 in 1

$4x-3(2x-3)+5=0$

$4x-6x+9+5=0$

$14=2x$

$7=x$

Substitute the value of x in 2

$2(2)-y-3=0$

$4-3=y$

$1=y$

So, Fraction = $\frac{x}{y}=\frac{7}{1}$

Hence The fraction is $\frac{7}{1}$

(1/3)9 to the third power =

AlekseyPX

The answer would be
1/3 * 9 = 3,
3^3 = 3*3*3, which then we multiply:
3*3=9, 9*3=27.
27 is the answer.

Hope this helps and have a nice day:)

$216 = 6^{4x+ 11}$

$6^3 = 6^{4x+ 11}$

$3 = 4x + 11$

$4x = 3 - 11$
