Because in the numerator and denominator of the fraction 1a/3a, you're able to simplify that and get 1/3. There is actually no solution to the problem you're asking. You're unable to find out what (a) equals.
B because distributive property goes like this:
a(b+c)
a(b)+a(c)
That's just an example though
Multiply 2/3 by the reciprocal, 3/2, on both sides.
