Question

how do you write these factions in simplest form

1/2 * 5/8 *4/5

-3/8 / 3/4

-16/9 / 8

Answer 1

`(1)/(2)\cdot(\\ot5)/(\\ot8_2)\cdot(\\ot4)/(\\ot5)=(1)/(2)\cdot(1)/(2)\cdot(1)/(1)=(1)/(2\cdot2)=\boxed{(1)/(4)}\\\\-((3)/(8))/((3)/(4))=-(3)/(8):(3)/(4)=-(\\ot3)/(8)*(4)/(\\ot3)=-(4)/(8)=\boxed{-(1)/(2)}\\\\-((16)/(9))/(8)=-(16)/(9):8=-(\\ot16^2)/(9)*(1)/(\\ot8)=\boxed{-(2)/(9)}`
