Question

So I need help with this

Answer 1

Answer:

-5/14

Step-by-step explanation:

2/7 times 2 to get the denominator to be 14 since adding and subtracting fractions require the same denominator. 2/7 times 2 = 4/14. -9/14+4/14=-5/14.

Answer 2

make them the same denominator

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

$\frac{ - 9}{14} + \frac{4}{14} = \frac{ - 5}{14}$
