Question

What is -2/3 - (-1/2)

Answer 1

Answer: -1/6

Step-by-step explanation: Start by changing the minus a negative

to plus a positive, so we have -2/3 + 1/2.

Since our denominators of 3 and 2 have no factors in common,

our least common denominator is 3 · 2 or 6.

In order to get a denominator of 6 in each fraction,

we multiply top  and bottom of the first fraction by 2

and top and bottom of the second fraction by 3.

That gives us -4/6 + 3/6 which simplifies to -1/6.

Answer 2

Answer:

$-\frac{1}{6}$

Step-by-step explanation:

$-\frac{2}{3}-(-\frac{1}{2})=\\\\-\frac{2}{3}+\frac{1}{2}=\\\\-\frac{4}{6}+\frac{3}{6}=\\\\-\frac{1}{6}$
