Question

How do you simplify `(12)/(5y^2) - 2/(5yz)`?

Answer 1

`(12z -2y)/(5y^2z) = (2(6z-y))/(5y^2z)`

Explanation:

Adding or subtracting fractions - algebraic and arithmetic -requires a common denominator.

`12/(5y^2) - 2/(5yz) " "LCD = 5y^2z`

`12/(5y^2) xx z/z - 2/(5yz) xx y/y"`

=`(12z -2y)/(5y^2z)`

This can also be written as `(2(6z-y))/(5y^2z)`
