Question

while baking, Evan discovered a recipe that required 1/2 cup of walnuts for every 2 1/4 cups of flour. How many cups of walnuts will he need for 4 cups of flour?

Answer 1

the ratio is 2 1/4:1/2, and for everything you do to one side, you do to the other, so, 2 1/4* 1.77777778=4, so 1/2*1.77777778=0.88888889
