Answer 2

1. $\frac{-2}{3} - \frac{4}{3}$

Here, we'll not subtract by using cross - multiplication method because the denominators of both the fractions are same.

So, we'll directly subtract - 2 from - 4 keepin' the denominator same. As,

$\frac{-2}{3} - \frac{4}{3}$

=> $\frac{-2 - 4}{3}$

=> $\frac{-6}{3}$

=> $\frac{\cancel{-6}}{\cancel{3}}$

=> - 2

2. $\dfrac{\dfrac{1}{125}}{\dfrac{1}{216}}$

=> $\frac{1}{125} \times \frac{216}{1}$

=> $\frac{216}{125}$

=> $\frac{6 \times 6 \times 6}{5 \times 5 \times 5}$

As 125 and 216 are perfect cubes of 5 and 6 respectively.

=> $\frac{6^3}{5^3}$
