Best ResponseYou've already chosen the best response.1Do you see what I did to solve for x? I used the first two fractions as a proportion, and solved the proportion for x. Are you ok so far?

Best ResponseYou've already chosen the best response.1Great. Now take the second and third fractions, and use them as a proportion and solve for y.

Best ResponseYou've already chosen the best response.1Now we want the ratio of x to y. The ratio of x to y can be written as x:y, and also as the fraction \(\dfrac{x}{y} \)

Best ResponseYou've already chosen the best response.0do we cross multiply them now ? the x y ?

Best ResponseYou've already chosen the best response.1Since we know what x and y are equal to, we write a ratio using those two numbers: dw:1439169044897:dw

Best ResponseYou've already chosen the best response.1We haven't finished yet. We now have a complex fraction, a fraction of fractions. We need to simplify it. Remember that a fraction means a division. dw:1439169173036:dw

Best ResponseYou've already chosen the best response.1To divide fractions, we multiply the first fraction by the reciprocal of the second one. Reciprocal is the math term that means to flip the fraction.
