Answer 2

To simplify the expression, let's first multiply the fractions together and then add the result to 98/128:

(1/2) * (3/4) * (5/6) * (7/8) + 98/128

Now, let's multiply the fractions:

(1/2) * (3/4) * (5/6) * (7/8) = (1 * 3 * 5 * 7) / (2 * 4 * 6 * 8)

= (105) / (384)

Now, we add this result to 98/128:

(105/384) + (98/128)

To add these fractions, we need a common denominator, which is 384. So, we'll convert 98/128 to have a denominator of 384:

(98/128) * (3/3) = (294/384)

Now, we can add the fractions:

(105/384) + (294/384) = (105 + 294) / 384

= 399 / 384

Now, let's simplify this fraction by finding the greatest common divisor (GCD) of 399 and 384, which is 3:

(399/3) / (384/3) = 133/128

So, the simplified result of the expression is 133/128.
