[tex] \frac{18}{25} \times \frac{5}{9} [/tex]
We can simplify the fractions first. If we look at the numerator of the first fraction and the denominator of the second fraction, we can change 9 into 1 and 18 into 2 since 18 is a multiple of 9. Likewise, we can change 5 to 1 and 25 to 5 since 25 is a multiple of 5.
[tex] \frac{2}{5} \times \frac{1}{1} = \frac{2}{5} [/tex]
The answer is 2/5.
