Multiple Choice

Dave is four years old. Tracy is twice Dave's age. How old is Tracy?

Explanation:
Being twice someone’s age means you double the smaller number. Dave is four years old, so twice Dave’s age is 2 × 4 = 8. That makes Tracy eight years old. The other possibilities don’t fit because 4 would mean Tracy is the same age as Dave, 6 isn’t twice 4, and 12 would be three times 4.

Being twice someone’s age means you double the smaller number. Dave is four years old, so twice Dave’s age is 2 × 4 = 8. That makes Tracy eight years old. The other possibilities don’t fit because 4 would mean Tracy is the same age as Dave, 6 isn’t twice 4, and 12 would be three times 4.
