Respuesta :

27/70 is the fraction
To do this multiply the numerators together (the tops together) and the denominators together (the bottoms together)

[tex] \frac{3}{7} * \frac{9}{10} [/tex]

= [tex] \frac{27}{70}[/tex]

27/70 is your answer in simplest form because you can't take the same thing out of the top or bottom anymore.

I hope this helps!
