The denominator always has to be the same
Example: 1/3 plus 2/4
we know that the LCM (least common multiple) is 12 so you do 1 times 4 and 3 times for because what you do to the bottom, you have to do to the top and for 2/4 we multiply 2 times 3 and 4 times 3 that will leave us with 4/12 plus 6/12 and then you get 10/12 then you reduce that to 5/6. I hope this helps if it doesn't go to Khan Academy its a website and its on Youtube. Good Luck!

Please help me solve the expression for “n”

Bingel [31]

Answer:

n = 2

Step-by-step explanation:

In order for the ratio to have a value of 1, the sum of exponents in the numerator must equal the sum of exponents in the denominator:

n + 7 = 9

n = 9 -7 . . . . . . subtract 7 from both sides of the equation

n = 2

___

Alternatively, you can simplify the given expression:

$\dfrac{9^n(9^7)}{9^9}=1=\dfrac{9^n}{9^2}$

Hopefully, it is clear to you that the value of n must be 2 in order to make the numerator equal to the denominator.
