Question 1199196
the ratio of cups of butter to cups of flour = 2/3.
let x = the number of cups of butter to cups of flour.
when she used 8 cups of flour, you get:
2/3 = x/8
cross multiply to get 3x = 16
solve for x to get:
x = 16/3 cups of butter.
that's 5 and 1/3 cups of butter.


confirm that the ratio of cups of butter to cups of flour has been preserved by taking (16/3) and dividing it by 8 to 16 / 24 = 2/3.
