i need help also i small brain

some one i need help with this 

Just  multiply  numerators and  denominators

So

3/4  x   4/19  x  6/8

One  of the  nice  things about  multiplying fractions  is that  we  can rearrrange numerators and denominators....also we can  reduce, where possible...so we can do the  following :

4/4  x  3/19 x 3/4   =

1   x    3/19 x 3/4   =        (3 * 3)  / (19 * 4)   =    9 / 76       and that's it  !!!!
