Answer 1

I think it's C

Answer 2

You can solve this either with the understanding that multiplying a fraction by it's reciprocal will give the value of 1 (this 3/8 * 8/3 = 1) or by solving for the variable:

3/8 * 8/b = 1

3 * 8 / 8 * b = 1

24 / 8b = 1

3/b = 1

3 * b/b = 1 * b

3 = b

Answer 3

You are correct, by the way.
