Please write down the whole thing, not just the question, because it's not quite easy to understand this way. Anyhow, you cannot cross cancel these two. 23 is a prime number.

You can't cross cancel these two, but you can cross cancel four and six, so that you have $\frac{45*2}{23*3}$ So you have $\frac{90}{69}$ Now you can divide both denominator and numerator by 3 getting 30/23
