what is the LCD of the following fractions: negative 2/3n and 7/3?
\(\bf \cfrac{2}{3n}\qquad \cfrac{7}{3}\\ \quad \\ \textit{a value or expression that can be divided by both}\\ \quad \\ \cfrac{{\color{blue}{ \cancel{3n}}}}{\cancel{3n}}\implies 1\qquad \qquad \cfrac{{\color{blue}{ \cancel{3}n}}}{\cancel{3}}\implies n\)
im confused...
hmm ok... do you know what an LCD is?
my choices are 14, 3, 3n, and 9n. and yes, the LCD is the least common denominator. @jdoe0001
least common denominator <--- what does that mean?
the smallest number that two or more denominators can go into.
right
well, in this case, you also have an "n" in the denominator... so it'd be the smallest expression \(\bf \cfrac{2}{3n}\qquad \cfrac{7}{3}\\ \quad \\ \textit{a value or expression that can be divided by both}\\ \quad \\ \cfrac{{\color{blue}{ \cancel{3n}}}}{\cancel{3n}}\implies 1\qquad \qquad \cfrac{{\color{blue}{ \cancel{3}n}}}{\cancel{3}}\implies n\)
see it?
kind of..... i just dont know what to do next
\(\bf \cfrac{{\color{blue}{ \cancel{3n}}}}{\cancel{3n}}\ or \ 3n\div3n\implies 1\qquad \qquad \cfrac{{\color{blue}{ \cancel{3}n}}}{\cancel{3}}\ or \ 3n\div3\implies n\)
so it would be 3n?
or just 3?
3n is the dividend, it can be divided by 3 and 3n
ok thanks
