Problem: the hcf and lcm of two numbers m and n are respectively 8 and 200 . if m + n = 84 , then 1 / m + 1 / n is equal to
Rationale: "answer we have , m x n = 8 x 200 = 1600 â ˆ ´ 1 / m + 1 / n = ( m + n ) / mn = 84 / 1600 = 3 / 50 correct option : b"
annotated_formula: divide(84, multiply(8, 200))
