Let x = 0.121212...
Then, 100x = 12.121212...
Subtracting the two equations, 100x - x = 12.121212... - 0.121212...
Simplifying, 99x = 12
Dividing both sides by 99, x = 12/99
Therefore, the fully simplified fraction is 12/99.

Evaluate: 8×8−6×2
To evaluate 8 × 8 - 6 × 2, we first perform the multiplications:
8 × 8 = 64
6 × 2 = 12
Next, we subtract the result of the second multiplication from the result of the first multiplication:
64 - 12 = 52
Therefore, the value of the expression is 52.
8 × 8 = 64
6 × 2 = 12
Next, we subtract the result of the second multiplication from the result of the first multiplication:
64 - 12 = 52
Therefore, the value of the expression is 52.
Evaluate: −4/2^2−(7−4)
To evaluate -4/2^2 - (7 - 4), we begin by working within the parentheses:
7 - 4 = 3
Now, we follow the order of operations and evaluate the exponent:
2^2 = 4
Next, we substitute the results back into the expression:
-4/4 - 3
Finally, we perform the division and subtraction:
-1 - 3 = -4
Therefore, the value of the expression is -4.
7 - 4 = 3
Now, we follow the order of operations and evaluate the exponent:
2^2 = 4
Next, we substitute the results back into the expression:
-4/4 - 3
Finally, we perform the division and subtraction:
-1 - 3 = -4
Therefore, the value of the expression is -4.
