a certain recipe calls for 4/5 cups of flour. A chef is making an amount that is 5/7 of the recipe. How much flour should the chef use?
Answer provided by our tutors
x = the cups of flour the chef should use
4/5 : 1 = x : 5/7
cross multiply
x = (4/5)*(5/7)
x = 4/7 cups of flour
the chef should use 4/7 cups of flour.
