Calculating Total Ingredients for a Recipe

Maria has a recipe that requires two fractions of ingredients: 3/4 of a cup of sugar and 2/5 of a cup of butter. She wants to prepare a double batch of the recipe. What is the total amount of sugar and butter she needs for the double batch?

To find the total amount of each ingredient needed, first calculate the amount required for one batch, and then double that amount. Consider how to add the two fractions together correctly.
