Alan is 14 years old. he is twice as old as his brother James. how old is James?

You take 14 and divide it by 2; 14/2=7

Alan is 14 years old

He is twice as old as James

then Alan is the elder brother

Alan is twice as old means his age is double the age of James

Alans age = 2 x james age

that means James must be half of Alans age

Alans age = 14 years

James age = 14 / 2 = 7 years

therefore James is 7 years old
