hello, Phebe!
Here you have two fractions with different denominators and need to combine them into one fraction.

Suppose you were trying to add 1/3 and 1/4.  See how the denominators are different?
We'd find the LCD (lowest common denominator) by multiplying the 2 denominators together, obtaining 12.  Thus, 12 is the lcd.

Write out your sum:$$\frac{ 1 }{ 3 }+\frac{ 1 }{ 4 }$$

ok so wat do i do

mathmale · Answer

Now multiply both numerator (1/3  +  1/4) by 12, and divide the whole thing (the whole result) by 12:$$\frac{ 12(\frac{ 1 }{ 3 }+\frac{ 1 }{ 4 } }{ 12 }$$

Can you simplify this?  Hint:  12(1/3) = 4, and 12(1/4) = ??
