if you multiply the numerator 3 and the denominator 7 from 3x/7, do you get 21?

No, multiplying the numerator 3 and the denominator 7 from 3x/7 does not give you 21. It would give you (3 * 3x) / (7 * 1) = 9x / 7.
what about 3x/10?
If you multiply the numerator 3 and the denominator 10 from 3x/10, you would get (3 * 3x) / (10 * 1) = 9x / 10.
