Question

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

Answer 1

Answer:

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

Step-by-step explanation:

$\tt 2+\left(-\cfrac{2}{3}\right)2\div \cfrac{1}{3}$

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

$\tt 2+\cfrac{\cfrac{-2\times 2}{3} }{\cfrac{1}{3} }$

Multiply -2 × 2 = -4

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

Now, rewrite fraction $\tt \frac{-4}{3}$ as $\tt -\frac{4}{3}$ 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

$\tt 2-\cfrac{4}{3} \times 3$

Cancel out 3 and 3:

$\tt 2-4$

Subtract numbers:

$\tt -2$
