%28%286a%29%2F%282b%29%29%2A%28%2812b%29%2F%283a%5E2%29%29 Start with the given expression.


%28%286a%29%2812b%29%29%2F%28%283a%5E2%29%282b%29%29 Combine the fractions.


%286%2A12ab%29%2F%286a%5E2%2Ab%29 Multiply


%286%2A12ab%29%2F%286a%2Aa%2Ab%29 Rewrite a%5E2 as a%2Aa


Highlight the common terms.


Cancel out the common terms.


12%2Fa Simplify.


So %28%286a%29%2F%282b%29%29%2A%28%2812b%29%2F%283a%5E2%29%29=12%2Fa where none of the variables are zero.
