How to write  9/18 into a equivalent fraction

Answer 1

There are many ways. $\frac{9}{18}$ is actually the same as $\frac{1}{2}$ so anything you do just has to have a numerator exactly half as the denominator. So one that would work is $\frac{18}{36}$ I just doubled both numbers. Other ones would be $\frac{5}{10} and \frac{6}{12}$ all of which the numerator is exactly half the denominator.
