If y is the reciprocal of 2, whats the difference between the reciprocal of 3y and 5y?

Question

I need someone to explain the answer step by step, not just give me the answer. thanks :)

Answer 1

"Solution: Given y is the reciprocal of 2 means y=1/2
then the difference between reciprocal of 3y and 5y=1/3y-1/5y=2/3-2/5=4/15
the difference =4/15"
How to Solve Reciprocal Equations Reciprocal equation can be defined as an algebraic equation in which only one variable is unknown and whose roots are unchanged when unknown is replaced by its reciprocal. We know that reciprocal is inverse of given number. Reciprocal equation can also be defined as equation which includes reciprocal of given variable (unknown variable).
