Answer 1

`(7)/(12)`

Step-by-step explanation:

Well, I'm not sure how you get your answer but see below for steps for how i get my answer;

`(1)/(4)-2\sqrt[3]{-(1)/(216)}`

`2\sqrt[3]{-(1)/(216)}=-2*(1)/(6)`

`=(1)/(4)-(-2*(1)/(6))`

`(1)/(4)-(-2*(1)/(6))=(7)/(12)`

`=(7)/(12)`

Thus, the answer is 7/12

Answer 2

`\sf (7)/(12)`

Step-by-step explanation:

`\hookrightarrow \sf (1)/(4)-2\sqrt[3]{-(1)/(216)}`

we should know the following
`\sqrt[3]{-(1)/(216) } = -(1)/(6)`

`\hookrightarrow \sf (1)/(4)-\left(2 * -(1)/(6)\right)`

`\hookrightarrow \sf (1)/(4)-\left(-(1)/(3)\right)`

`\hookrightarrow \sf (1)/(4)+(1)/(3)`

`\hookrightarrow \sf (7)/(12)`
