Question

Good evening, can you explain and give a result please, thanks

Answer 1

given equation is,

`-\mleft(-2\mright)(-(2)/(3))(-(1)/(2))(-(5)/(6))\mleft(-3\mright)`
`\begin{gathered} -(-2)(-(2)/(3))(-(1)/(2))(-(5)/(6))(-3) \\ =2\cdot(2)/(3)\cdot(1)/(2)\cdot(5)/(6)\cdot\: 3 \\ =(2\cdot\:1\cdot\:5\cdot\:2\cdot\:3)/(3\cdot\:2\cdot\:6) \\ =(1\cdot\:5\cdot\:2\cdot\:3)/(3\cdot\:6) \\ =(1\cdot\:5\cdot\:2)/(6) \\ =(10)/(6) \\ =(5)/(3) \end{gathered}`
