Answer:
The answer is 3, but here’s how I got that answer.
Explanation:
As we know the trifle recipe requires 1 ½ cups of sugar, and the chocolate cake requires double the amount of sugar.
You have two options.
Multiply 1½ by 2
1½ x 2 = 3
———————————
Or add 1½ + 1½
1½ + 1½ = 3

Wasn’t sure what you were asking for with this this question, but hope it helped.
