Answer 2

Calculations with x and y

1) Sum of the reciprocals of x and y: - The sum of the reciprocals of x and y is given by 1/x + 1/y. - Therefore, the sum is (1/x) + (1/y).

2) Ratio of the sum of a and b to their difference: - The ratio of the sum of a and b to their difference is given by (a + b) / (a - b). - Hence, the ratio is (a + b) / (a - b).

3) Number opposite to the sum of x and y: - The number opposite to the sum of x and y is the negative of the sum, i.e., -(x + y). - Therefore, the number is -(x + y).
