Question

Ryan made 104/7 gallons of cider for his party. His guests drank 61/2 gallons in all. About how much cider does Ryan have left?

Answer 1

Do you know how to find the least common denominator?

Answer 2

\(\bf \cfrac{104}{7}-\cfrac{61}{2}\implies \cfrac{}{{\color{red}{ \textit{what's the lcd?}}}}\)

Answer 3

ok, so example the least common denominator of 3 and 4 would be 12. That is the smallest number able to be divided by both 3 and 4 evenly.

Answer 4

Can you do it for 2 and 7?

Answer 5

Did you get it?
