Please help solve 16/21 divide 15/14 times 5/4

It's been a long time since I've done fractions.

16/21 divided by 15/14 x 5/4 =
16/21 divided by 75/56 =
16/21 x 56/75 =
128/225.

[(16/21)*(14/15)]*(5/4)=(32/45)*(5/4)=8/…

(16/21)/(15/14)*5/4
= (16/21)*(14/15)*(5/4)
= (16*14*5)/(21*15*4)
= (16/4)(14/21)(5/15)
= (4)(2/3)(1/3)
= 8/9
