Question

What is the sum of -2/3 and -4/6

Answer 1

Make sure they have common denominators.

-2/3 x (2/2) = -4/6

-4/6 + -4/6  = -8/6

-8/6 = - 1 2/6

-1 2/6 or -1 1/3 simplified, is your answer

hope this helps

Answer 2

To add these fractions, we need to make them have the same denominator.  Luckily, 4/6 simplifies to 2/3:

$-\frac{2}{3} +(- \frac{2}{3} )$

Adding a negative number is subtraction, so our problem now looks like this:

$-\frac{2}{3} - \frac{2}{3}$

$-\frac{4}{3}$

The sum of  -2/3 and -4/6 is -4/3, or - 1 1/3.
