nope

Answer 3

Answer 4

sorry bad lag :/

Answer 5

ok sorry

Answer 6

a good way to find the LCD is to math it out:
\[\frac19+\frac1{12}=n\]
and start with the largest denominator and multiply it thru
\[\frac{\cancel{12}^4}{\cancel{9}^3}+\frac{12}{12}=12n\]
\[\frac43+1=12n\]and do it again
\[\frac{12}3+1(3)=12(3)n\]
\[4+1(3)=\underbrace{36}_{LCD}~n\]

Answer 7

ty that's what I thought it was!
