Can someone please explain this to me in detail? Thank you! To make 4 3/5 cakes, 2/3 pounds of flour is needed. How much flour is needed to make one cake?

Divide.

(2/3) / (4 3/5) =

(2/3) / (23/5)

(2/3) * (5/23) = 10/69 pound
the amount of flour needed is directly proportional to the number of cakes...more cakes, more flour

the constant of proportionality (k) is the flour per cake

4⅗ * k = 2/3

dividing both sides by 4⅔

k = 10/69 lb/cake

seems more like a cupcake...
4 3 / 5 = 4 + 3 / 5 = 4 * 5 / 5 + 3 / 5 = 20 / 5 + 3 / 5 = 23 / 5

( 2 / 3 ) / 4 3 / 5 =

( 2 / 3 ) / ( 23 / 5 ) =

2 * 5 / ( 3 * 23 ) =

10 / 69 pounds
