Best ResponseYou've already chosen the best response.3\(\large\rm 8=2\cdot4\) \(\large\rm 10=2\cdot5\) \(\large\rm LCM(8,10)=2\cdot4\cdot5=40\) Ok good!

Best ResponseYou've already chosen the best response.3\[\large\rm \frac{5}{8}\frac{3}{10}\color{royalblue}{\frac{4}{4}}\]To get that denominator, clearly the second fraction needs a 4. What about the first one? :o

Best ResponseYou've already chosen the best response.3Ok good.\[\large\rm \color{royalblue}{\frac{5}{5}}\cdot\frac{5}{8}\frac{3}{10}\cdot\color{royalblue}{\frac{4}{4}}\]

Best ResponseYou've already chosen the best response.3So we know the denominators will be 40, we worked that out already,\[\large\rm \frac{5\cdot5}{40}\frac{3\cdot4}{40}\]Can you figure out the tops? :)
