Amuffin recipe, which yields 12 muffins, calls for cup of milk for every 1 cups of flour. the same recipe calls for cup of coconut for every cup of chopped apple. to yield a batch of 30 muffins, how much flour will be needed in the mix?

For each proportion find the unknown number x 1/5/8=×/15

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)
