Question

Add or subtract the fractions. Write the answer in simplified form.-2/13+(-1/13)

Answer 1

1) To add or subtract fractions, let's firstly check the denominators

In this case, the denominator is the same.

The plus before the bracket does not change the sign.

`\begin{gathered} -(2)/(13)+(-(1)/(13)) \\ (-2-1)/(13) \\ \\ (-3)/(13) \end{gathered}`

That is why we get to -3/13 as a result.
