Best ResponseYou've already chosen the best response.1So suppose you have a fraction \[\Large \frac{5/4}{7/3}\]Then this can be simplified by doing \[\Large \frac{5}{4}\times\frac{3}{7}=\frac{15}{28}\]

Best ResponseYou've already chosen the best response.1For another example, if you have \[\Large \frac{5/4}{7}\]Then this is the same thing as \[\Large \frac{5/4}{7/1}=\frac{5}{7}\times \frac{1}{4}=\frac{5}{28}\]

Best ResponseYou've already chosen the best response.0Interestingly enough, \(\large 5/4 ÷ 7/3 = \frac{5÷7}{4÷3} = 5/7 ÷ 4/3.\)

Best ResponseYou've already chosen the best response.1Now using the examples I just gave, can you tell me what \[\Large \frac{3/2}{6/5}\]can be simplified to?

Best ResponseYou've already chosen the best response.0In general we can say when you divide, a\[(a \div b)\div(c \div d) = (a \div b)\times(d \div c)\]

Best ResponseYou've already chosen the best response.1Now, let's mix it up a bit. What about \[\Large \frac{8}{2/5}\]If this is a bit confusing, try turning the 8 into a fraction and seeing what you can do then.

Best ResponseYou've already chosen the best response.1Right again. I think you're getting the hang of this. Does this help you with the problems you were given?

Best ResponseYou've already chosen the best response.1I strongly believe in the power of varying examples that are usually more difficult than necessary.
