Hey there, Megan1321!
This question is basically saying that 5 is half of what number.
The answer is 10 because half of 10 is 5
Whenever you have a question that says 5 = 1/2 of ____, you need to multiply that number by 2 to get the double number, or the number you need. If it's 5 = 1/3 of ____ you just multiply it by 3 and you get 15 and so on
