Question

Find −9/14 + 2/7. Write your answer as a fraction in simplest form.

Answer 1

Answer:

$-\frac{5}{14}$

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:

$\frac{2 * 2}{7 * 2} = \frac{4}{14}$

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:

$\frac{-9 }{14} + \frac{4}{14}$

==> $-\frac{5}{14}$

Answer 2

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