D/3y - m/6y simplify

(2d - m) / 6y

Step-by-step explanation:

To simplify, we must first find the lowest common multiple (LCM) of the denominators which are 3y and 6y.

The LCM of 3y and 6y is 6y. We then make it the common denominator while we multiply the numerators with it.

Hence,

d/3y - m/6y

= (6y (d/3y) - 6y (m) / 6y) / 6y

Dividing and multiplying

= (2d - m) / 6y
