Respuesta :

-5/14 (change 2/7 to 4/14 and it’ll help)

Answer:

[tex]-\frac{5}{14}[/tex]

Step-by-step explanation:

When you add fractions, sometimes you have to raise a number to make it more easier for you.

As in this case, we have two fractions in which seem to not be the same, but note this.

7 is multiple of 14, meaning to make our life easier, we can do this method:

[tex]\frac{2 * 2}{7 * 2}  = \frac{4}{14}[/tex]

Whoa! Now we have the same denominator for both fractions, now we made this problem way more easier than it was before.

Do the math:

[tex]\frac{-9 }{14} + \frac{4}{14}[/tex]

==> [tex]-\frac{5}{14}[/tex]
