Um... What's "the flying X"?
weaselgopher wrote:[(1)/(2a+2b)] + [(a)/(a+b)] which i think gets to [(a+b) + a(2a+2b)]/[(2a+2b)+(a+b)] and then I'm not sure.
To add these fractions
, you need to convert to a common denominator. The two denominators are 2(a + b) and (a + b), so 2(a + b) will be the least (smallest and simplest) common denominator.
The first fraction already has the common denominator. To convert the second fraction to the common denominator, multiply top and bottom by 2:. . . . .
Then add:. . . . .
Fill in the numerator to complete the exercise.
