Answer:
3/200
Step-by-step explanation:
Given x+y = 27
HCF x LCM = xy = 30*60 = 1800
Sum of reciprocal = 1/x + 1/y = (x+y)/xy = 27/1800 = 3/200
The trick to do this problem is to remember the property of LCM and HCF of two numbers. The product of LCM and HCF of 2 numbers is always equal to the product of the numbers.
