Question

Helpppp pleaseeee ee​

Answer 1

`-12`

Explanation:

Given that:

`a=(1)/(4) \\b=6`

To evaluate the expression
`-8ab`, we must simply substitute the given values into the expression, and solve:

`-8((1)/(4) )(6)`

Multiply
`-8` and 6:

`-48*(1)/(4)`

Cross-cancel by dividing
`-48` and
`4` by
`4`:

`-(12)/(1) *(1)/(1)`

Multiply:

`-12`

Answer 2

✐
`\underline{ \underline{ \sf{Given \: values}}} :`

• a =
  `\sf (1)/(4)`
• b = 6

✐
`\underline{ \underline{ \sf{ \: To \: find : }}}`

• -8ab

`\sf{Plug \: the \: given \: values} :`

⟼
`\tt{ - 8 * (1)/(4) * 6}`

⟼
`\tt{ ( - 8 * 1 * 6)/(4)}`

Remember : Multiplying negative integer by positive integer gives a negative integer.

⟼
`\tt{ ( - 48)/(4) }`

Remember : Dividing negative integer by positive integer gives a negative integer.

⟼
`\sf{ \boxed{ - 12 }}`

`\red{ \boxed{ \boxed{ \bold{ \purple{\tt{Our \: final \: answer : - 12}}}}}}`

Hope I helped ! ツ
