add 1/2 + 2/3 and get 3/6 +4/6 = 7/6 then multiply by 1/2 and get 7/12 the number 1/2 way between them. multiplying by 1/2 is the same as dividing by 2 which is how we average two numbers Solution add 1/2 + 2/3 and get 3/6 +4/6 = 7/6 then multiply by 1/2 and get 7/12 the number 1/2 way between them. multiplying by 1/2 is the same as dividing by 2 which is how we average two numbers.
