I will like to know how you simplify this

Question

-4/7+(-4/3)=

Answer 1

$\frac{-4}{7}-\frac{4}{3}$ = $\frac{(-12-28)}{21}$ = $\frac{-40}{21}$

If you don't understand how to get and use a common denominator, please send me a message.

Answer 2

Convert both terms so they have a common denominator.

4/7 = (4/7)(3/3) = 12/21

4/3 = (4/3)(7/7) = 28/21

-4/7 - 4/3 = -12/21 - 28/21 = -(12 + 28)/21 = -40/21
