Question

What is the value of 2 + (-
12=1?
-2
16
031

Answer 1

`\boxed{\boxed{\tt B)-2}}`

Explanation:

`\tt 2+\left(-\cfrac{2}{3}\right)2/ \cfrac{1}{3}`

Express -2/3 × 2 as a single fraction:

`\tt 2+\cfrac{\cfrac{-2* 2}{3} }{\cfrac{1}{3} }`

Multiply -2 × 2 = -4

`\tt 2+\cfrac{\cfrac{-4}{3} }{\cfrac{1}{3} }`

Now, rewrite fraction
`\tt (-4)/(3)` as
`\tt -(4)/(3)` by extracting the (-) sign:

`\tt 2+\cfrac{-\cfrac{4}{3} }{\cfrac{1}{3} }`

Divide - 4/3 by 1/3 by multiplying - 4/3 by the reciprocal → 1/3

`\tt 2-\cfrac{4}{3} * 3`

Cancel out 3 and 3:

`\tt 2-4`

Subtract numbers:

`\tt -2`
