need help badly. this is the math problem.
is the rate threeforth's cup of butter/ 3 eggs equivalent to the rate of 3 cups of butter/12 eggs?
Please show the work so I can study this equation for my next problem. thanks kindly

One way to solve this problem is with a proportion.
(3/4) / 3 = 3 / x
Cross multiply and solve for x.
(3/4)x = 9
x = 9 / (3/4)
x = 9 * (4/3)
x = 36/3 = 12
