To multiply a rational number(fraction), you multiply across the numerators and denominators. For example: [tex] \frac{A}{B} [/tex]×[tex] \frac{X}{Y} [/tex]=[tex] \frac{AX}{BY} [/tex] or if [tex] \frac{3}{5} [/tex]×[tex] \frac{3}{6} [/tex]=[tex] \frac{9}{30} [/tex] which you need to reduce by 3 since it is a common multiple [tex] \frac{9}{30} = \frac{3}{10} [/tex]
