23. Jill was making fudge. The recipe called for 3/4 of a pound of chocolate, but Jill only had 2/5 of a pound of chocolate. What part of the recipe could Jill make?
We can use the A= RB technique. In this case the most natural rate that occurs to us is 3/4 lb per recipe. In that case the base would be recipes, so if we are looking for the number of recipes we should use the formuls B = A/R where A is 2/5 lb and R is 3/4 lb/recipe.
