blog...:(

so aleks thinks i'm stupid and wants to know if i can add fractions with common denominators. its SUPER difficult...(sarcasm) so here are some steps and an example for you slow folk. and i actually think i got a negative wrong on the assesment and had to do this module again! its really simple i promise. i would go over what ya'll did friday but i wasn't here and someone should really give me the notes tomorrow.

Problem: (4v-3w)/6v-(9v+5w)/6v

Each fraction has the same denominator, namely .
So we subtract the numerators and keep the denominator the same to get

(4v-3w)-(9v+5w)

----------------------

6v

Distributing the negative sign over the parentheses, we have

4v-3w-9v-5w

-----------------

6v

Combining like terms, we get

-5v-8w

---------

6v

This fraction cannot be simplified so that's the answer. have fun.
