An apple crisp recipe calls for 90 grams of white sugar and 55 grams of brown sugar. How many kilograms of sugar, including both white and brown, are needed to make 12 crisps?

90 grams are equivalent to 0.09 kilograms and 55 grams are equivalent to 0.055.

So 0.09 + 0.055 = 0.145.

0.145 * 12 = 1.74

So 1.74 kilograms of sugar is needed to make 12 crisps.

Total weight of fruit:

454 g + 50 g = 504 grams

Weight for 12 cakes:

504 grams * 12 = 6,048 grams

Weight for 12 cakes conversion:

6,048 grams = 6,048 : 1,000 = 6 remainder 48 = 6 kilograms Answer = 6 kilograms remainder 48 grams
