and
. Remember that if you multiply the denominator by a certain number, you must multiply the numerator by the same number as well. For example, in
, we multiply 3 by 5 and 2 by 5. Same number. Now with that out of the way, let's work on the equation:
+
. We know it is the same as
and
. So now all we do is add the numerators together: 5+10=15 or
. Now we have to reduce the fraction.
can be reduced to 3 by dividing 15 by 5=3. The final fraction is
or can be simply put as 3 since 3/3 is a whole number. That's it - you're done!
