Best ResponseYou've already chosen the best response.1Hmm the bottoms are different :O Makes them difficult to compare. Let's find the `least common multiple` of 4 and 7.

Best ResponseYou've already chosen the best response.1if we count by 4's and count by 7's, when do they meet? :)

Best ResponseYou've already chosen the best response.14, 8, 12, 16, 20, 24, 28 7, 14, 21, 28 28 ah good!

Best ResponseYou've already chosen the best response.1So we want a bottom of 28. \[\Large\rm \frac{3}{4}\cdot\color{royalblue}{\frac{7}{7}}\]See how this guy already has a 4 in the bottom? :d so we gotta give him a 7, ya?

Best ResponseYou've already chosen the best response.1Hmm this bottom already has a 7. I don't think we wanna give him another 7 in order to get to 28.

Best ResponseYou've already chosen the best response.1So we actually wanna give him a 4, ya?\[\Large\rm \frac{4}{7}\cdot\color{royalblue}{\frac{4}{4}}\]Because the 7 times 4 will give us that 28 that we were looking for.

Best ResponseYou've already chosen the best response.1So what do you get for that second fraction? :) Again, multiply top with top, bottom with bottom.

Best ResponseYou've already chosen the best response.1Ok good, So instead of comparing \(\Large\rm \frac{3}{4}\) and \(\Large\rm \frac{4}{7}\) we can get a common denominator and compare \(\Large\rm \frac{21}{28}\) and \(\Large\rm \frac{16}{28}\)
