1 Answer

Solution :-

let us subtract

\(\dfrac{ -7}{22} –\dfrac{ -8}{33}\)

By taking LCM for 22 and 33 which is 66

\(\dfrac{ -7}{22} – \dfrac{-8}{33} =\dfrac{ (-7×3)}{(22×3)} \)

\( – \dfrac{(-8×2)}{(33×2)} = \dfrac{-21}{66} –\dfrac{ -16}{66}\)

Since the denominators are same we can subtract directly

\(\dfrac{ (-21+16)}{66} = \dfrac{-5}{66}\)
