24/16=3/2
so multiply each ingredient by 3/2
3/2*2/3=1 cup of butter
3/2*5 ounces of chocolate 15/2=7.5 ounces of chocolate
1 1/2=3/2
3/2*3/2=9/4=2 1/4 cups of sugar
3/2*2=3 teaspoons of vanilla
3/2*2 eggs= three eggs
3/2*1= 3/2 cups of flour = 1 1/2 cups of flour

Scale all the ingredients up by a factor of 24%2F16+=+3%2F2
--------------------------------------------
2/3 cup butter >> 2%2F3%2A3%2F2+=+1 cup butter
5 ounces unsweetended chocolate >> 5%2A%283%2F2%29+=+7.5 ounces
1 1/2 cups sugar >> 1.5+%2A+%283%2F2%29+=+2.25 cups sugar
2 teaspoons vanilla >> 2%2A%283%2F2%29+=+3 teaspoons vanilla
2 eggs >> 2%2A%283%2F2%29+=+3 eggs
1 cup flour >> 1%2A%283%2F2%29+=+1.5 cups flour
